Technical Field

The present invention generally relates to the field of automatic faucets and pissoirs. More particularly, the present invention relates to upgrading of any type of already existing- installed conventional into automatic faucet by complementing, adding of control valve in series, and proximity sensors, all to be normally used, " everywhere and in every place" , in mode which is mixture of manual and automatic modes and exceptionally in only manual mode. Also, the present invention relates to upgrading of conventional angle valve for urinal into automatic one, in the same way as conventional faucet, all to be normally used in automatic mode and exceptionally in conventional mode, in public and all other places and circumstances where it is usually used. Similarly, the present invention relates to quite new faucets of any type which are almost, that is, like conventional ones but with small addition, with proximity sensors built in them, combining with control valve in series, all to be normally used " everywhere and in every place" , in mode which is mixture of manual and automatic modes and exceptionally in only manual mode.

Background Art

There are many reasons for automatic (hands free) faucets application have become actual in a pretty long period of time, like, saving water in both domestic and public circumstances, vandalism prevention in public application (in case of conventional faucet somebody could intentionally leave the faucet opened) , without touch activating (in conventional case dirty hands touch activating may need washing of the faucet lastly) , sanitary advantage especially in public circumstances, easier usage by handicapped and elderly, etc.

Typical hands free automatic faucet is with infrared proximity sensors or some other type, electrically connected to the control valve over control electronic, so that, detection of hands or some other object in the detecting zone causes the valve to be activated and opened, and vice versa.

It seems that automatic faucet like this, has been dominantly used so far in public circumstances, at least in Europe, comprising spout with sensors on it, mounted on the upper side of basin and control valve and control electronic mounted bellow the basin. Typically, the faucet deliver only cold water with constant flow, adjusted for once somewhere bellow basin, not provided user to do that, or, if provided cold and hot water to be mixed, the faucet deliver water of constant flow and constant temperature, adjusted for once somewhere bellow basin too, not provide user to do that, again. It is naturally, taking in account the application of the faucet.

Examples of the automatic faucets just explained are given in U.S. patent 6,082,407 to Paterson et al., and U.S. Patent Application 2008/0078019A1 to Allen JR. et al.

In U.S. patent 6,082,407 accent is on, placing of sensors, fluid conduit and battery-power supply for sensors, into the spout and providing of corrosion- resist ant assembly with high endurance finish. The used solenoid control valve is specified as conventional and no details about it discussed, so and type of power supply.

U.S. Patent Application 2008/0078019A1 has been explained the embodiment comprising spout, sophisticated wireless sensor unit dislocated from the spout and quite separately positioned somewhere, single (for both cold and hot water) or double (one for cold and one for hot water) control electronic units, single or double actuated valves, and two manual valves. The solution is pretty pour from the adjusting of flow rate and temperature point of view for these adjustments has done for once by means of manual valves. Double control electronic units and control valves makes the solution noneconomic and expensive. There is no discuss and details about control electronic units and valves, so and type of their power supply.

Some more similar examples with previous, but different only concerning their more kitchen than public applications, are given in U.S. Patent Application 2007/0157978 A 1 to Jonte et al. , and U.S. patent 7,537, 195B2 to McDaniel et al.

U.S. Patent Application 2007/0157978A1 has been presenting the solution which comprises spout, conventional manual valve, dislocated from the spout and connected in series with actuator controlled valve, control electronic and several different sensor systems, proximity, capacitive and touch sensors. Although the solution implies several sophisticated different modes, all it is pretty complicated and the whole unshared expensive system one should afford. There are no details about control electronic and control valve, so and type of its power supply.

U.S. patent 7,537, 195B2 has been explaining the solution especially focused to the position sensitive device. The device is very sophisticated in conjunction with control electronic as well to provide no false in detecting of an object inside the trigger zone. There are no any discussion about control valve, so and type of its power supply. The invention implies at least two modes, hands free mode and manual mode. The manual mode implies position sensitive device deactivated, but not said in which way, faucet control by a handle like conventional faucet but the handle is not presented and not discussed anyhow.

There are some other examples more specific than the previous presented, including original control valves. These are in CA patent application 2598906A1 to Jost et al., and U.S. patent application 2008/0163942A1 to Boey, and U.S. patent 7,464,418B2 to Seggio et al., and U.S. patent application 2009/0094740A1 to Ji.

In CA patent application 2598906A1 an automatic faucet has been presented comprising spout, capacitive type sensor, control electronic and original, mixer (valve) of hot and cold water as well as control valve both positioned bellow basin. Primarily, the power supply is from battery, but alternatively could be provided by hardwired alternating current. The invention is suitable for public application. The system is unshared and one should afford high expense of that.

U.S. patent application 2008/0163942A1 present the automatic faucet comprising spout for exiting of cold, hot, or several stages of mixture of cold and hot water, touch sensors, control valves, one, two or four, control electronic and power supply from transformer connected to alternating current source. Possible ratio of mixture of cold and hot water is not continuous but discrete. It recommends it only for public application. The faucet implies several modes but control is complicate. Power supply from alternate current network over transformer is expensive. One should afford the whole expensive system for it is unshared.

In U.S. patent 7,464, 418B2 the invention is consisted of like a conventional one handle faucet for cold and hot water to be mixed, proximity sensor, solenoid control valve connected in series with like conventional faucet, and control electronic. The like conventional faucet is still pretty different from stated conventional faucet for conventionally mixed warm water is not delivered through the spout outward but internally sent to solenoid control valve and then back to spout and outward. The like conventional faucet is still especially constructed for the purpose. The faucet implies two modes, manual and hands free. The sensor is infra red and positioned on the wall of faucet body. There is a cover ring rotatable around the faucet body so that, when the hole in the ring coincides with the sensor, sensor normally works within hands free mode, when the cover ring is rotated and its hole does not coincide with the sensor, the solenoid control valve is blocked in open state and the faucet is able to function as conventional in manual mode. Evidently, the two modes excludes each other. The whole system is unshared and expensive so that one should afford the expense of the whole system.

U.S. patent application 2009/0094740A1 presents the invention which is automatic faucet for cold and hot water to be mixed, with two modes, manual and hands free. The faucet comprises conventional valve controlled by a liver for adjusting flow and temperature, solenoid control valve connected in series with former one, both built in the main body, proxim- ity sensor on the main body, battery power supply for sensors and solenoid control valve and control electronic both outside from the main body. The invention implies the original solenoid control valve built in the main body, the hole system is unshared and expensive, so one should afford the expense of the whole system.

The aim is to give the invention which is automatic faucet with advantages compared to all known and previously presented solutions. The main motivation for that is saving of huge amount of the highest-quality water which becomes the critical worldwide resource. What is that, the upper mentioned, huge amount of water and how to save it? There is estimate that 75% of consumed water is wasted while one does something else but not directly uses the water, for example, souping hands or face, foaming and shaving of beard, teeth brushing, holding off of the rinsed dishes etc. To apply the intended invention massively "everywhere and in every place" . How to do that? To upgrade the existing, that is, already installed conventional both faucets only for cold water and faucets for cold and hot water to be mixed, into automatic residential and others faucets. The upgrading is realized by adding proximity sensors and especially developed control valve with extremely small energy consumption from battery power supply, connected in series with conventional faucet, in the water way from the water network to conventional faucet. The upgraded conventional faucet works in mode which is mixture of manual mode of conventional faucet and hands free mode. By the conventional faucet one adjusts flow or flow and/or temperature and after that leaves the adjusted parameters of water. Further, one uses the water of the adjusted parameters under hands free principle. Extremely small energy consumption from battery guarantees its long life of several years. The batteries are common or lithium. Common batteries and their long lives means small expense. Keeping of existing conventional faucet and achieving relatively small cost of control valve also means small expense. The result is, necessary comfort, great benefit, but with small expense.

Disclosure of the Invention

The idea of the invention is that to be applied massively " everywhere and in every place" in which way huge amount of water would be saved, for, there is estimate that 75% of consumed water is wasted while one does something else but not directly use the water, for example, souping hands or face, foaming and shaving of beard, teeth brushing, holding off of the rinsed dishes etc, concerning faucets and that to be applied to pissoirs in which way water is consumed in automatic working regime only after usage, differently compared to the conventional working regime when water is consumed always.

Global embodiment of the invention concerning conventional water faucets of any type, whether they are already existing- installed or quite new, almost the same as conventional ones except with proximity sensors built in it, which are used or to be used anywhere, "everywhere and in every place" , as well as concerning conventional angle valve for urinal, which both are complemented, into automatic ones, by control valve in series, proximity sensors except when it is built in new conventional faucets, and control electronic, all autonomously powered by own battery. The resulting automatic devices, automatic faucet and automatic angle valve for urinal, are nominally to be used, faucet in mode which is mixture of manual and automatic hands free modes, and angle valve for urinal in automatic mode, and excep- tionally, both faucet and angle valve for urinal, in only manual mode and conventional mode, respectively, when the automatic system is malfunctioned. The control valve of magnetically latching pilot-controlled solenoid valve type is especially developed for the purpose, with ex- tremely small energy consumption. As an alternate, any type of the solenoid valve could be used as control valve but with no guarantees the power consumption would be extremely small. By the conventional faucet and conventional angle valve for urinal, parameters of water which is flow through them are adjusted and after that the water of the adjusted pa- rameters is used, under hands free principle, that is, under automatic regime. Reuse of the faucet possibly means readjust of water parameters and further use that readjusted water parameters. Similarly, if necessary, the water parameter could be possibly readjusted by conventional angle valve for urinal again. In that way water is consumed rationally only when it is actually used.

Best Modes for Carrying Out of the Invention

According (Related) to the invention, global, general embodiment which is essence of the invention and several illustrative and preferred embodiments are presented. Global, general embodiment of the invention is upgrading of the conventional water faucets of any type or conventional angle valve for urinal, into automatic faucets which are used anywhere "everywhere and in every place" and automatic angle valve for urinal, by complementing them with some other components. The first one is upgrading of the existing, that is, already installed conventional faucets only for cold water into automatic residential and others faucets. Further one is with quite new faucets only for cold water which are almost, that is, like conventional ones but with small addition, with proximity sensors built in them, combining with control valve in series, into automatic residential and others faucets. Another one is upgrading of the existing, that is, already installed conventional faucets for cold and hot water to be mixed, into automatic residential and others sink or kitchen faucets. Further one is with quite new faucets for cold and hot water to be mixed, which are almost, that is, like conventional ones but with small addition, with proximity sensors built in them, combining with control valve in series, into automatic residential and others sink or kitchen faucets. Next one is almost quite the same as one of the previous, concerning upgrading of already existing, that is, installed conventional faucet for cold and hot water to be mixed, into automatic one, which is primarily used in kitchen circumstances. The following one is related to the quite new faucet for cold and hot water to be mixed, which is almost, that is, like conventional one but with small addition, with proximity sensors built in it, combining with control valve in series, into automatic one, which is primarily used in kitchen circumstances. The last one is upgrading of existing, that is, already installed conventional angle valve for urinal into automatic one. Global embodiment of the invention concerning conventional water faucets of any type, whether they are already existing-installed or quite new, almost the same as conventional ones except with proximity sensors built in it, which are used or to be used in residential and all other places and circumstances where it is normally to be used, as well as concerning conventional angle valve for urinal, which both are complemented, into automatic ones, by control valve in series, proximity sensors except when it is built in new conventional faucets, and control electronic, all autonomously powered by own battery. The resulting automatic devices, automatic faucet and automatic angle valve for urinal, are nominally to be used, faucet in mode which is mixture of manual and automatic hands free modes, and angle valve for urinal in automatic mode, and exceptionally, both faucet and angle valve for urinal, in only manual mode and conventional mode, respectively, when the automatic system is malfunctioned. The control valve of magnetically latching pilot-controlled solenoid valve type is especially developed for the purpose, with extremely small energy consumption. As an alternate, any type of the solenoid valve could be used as control valve but with no guarantees the power consumption would be extremely small, what is one of the main and essential property of the invention, so that it would be autonomous, that is, the power supply to be from battery of long life without often changing. By the conventional faucet and conventional angle valve for urinal, parameters of water which is flow through them are adjusted and after that the water of the adjusted parameters is used, under hands free principle, that is, under automatic regime, respectively. Reuse of the faucet possibly means readjust of water parameters and further use that readjusted water parameters. Similarly, if necessary, the water parameter could be possibly readjusted by conventional angle valve for urinal again. In that way water is consumed rationally only when it is actually used.

Figures 1 and 2 show structural diagrams of the global, general embodiment of the invention, concerning conventional water faucet of any type and conventional angle valve for urinal, respectively, which are upgraded into automatic faucet and automatic angle valve for urinal, what is all generally indicated at 00. The embodiment comprises the conventional water faucet or angle valve for urinal 01 , the sensor assembly 10, originally developed valve assembly 20, toggle valves 70 and 80, shut-off valves 90 and water lines. Preferably, water enters the system from the wall water network. Related to the conventional angle valve for urinal 01, water directly enters it, but in the case of faucet, also 01 , of any type, it enters through the shut-off valves 90. In the case of faucet, double arrow goes, from the wall water network, to shut off valves, what symbolically means that it could represents double water lines, for example, one for cold water and one for hot water in the case of faucet for cold and hot water. In the case of faucet only for cold water, it represents single water line for cold water. In the case od angle valve for urinal, mentioned arrow, from the wall water network, to the angle valve for urinal itself, is single, and represents single water line for cold water. Further, in both cases, water goes over toggle valves, alternatively, to the control valve of the valve assembly 20 or to the toggle valves 80, what depends of two working positions of toggle valves 70, which are compatible with two system working regimes, automatic and conventional in the case of angle valve for urinal, and one which is mixture of the manual and hands free modes, and another one which is conventional manual mode, in the case of faucet. In the case of faucet, double arrows go, from shut off valves 90 to toggle valves 70, as well as, from toggle valves 70, alternatively, to control valve of valve assembly 20, or toggle valves 80. These double arrows, also, symbolically means that it could represents double water lines, in the case of faucet for cold and hot water. In the case of angle valve for urinal, the mentioned arrows from the valve itself to the toggle valve 70, as well as from the toggle valve 70, alternatively, to the control valve of valve assembly 20, or to the toggle valve 80, are single what represents single water lines for cold water. One of two working modes of toggle valves 70 is selected manually by means of its handle for the purpose. The toggle valves 70 are operably connected, to the originally developed control valve of valve assembly 20, and toggle valves 80. Control valve of valve assembly 20 is double variant, single in the case of angle valve for urinal and a faucet for only cold water, and double in the case of a faucet for cold and hot water. Also, control valve of valve assembly 20 is operably connected to the toggle valves 80. The toggle valves 80 are operably connected with spout to the urinal in the case of angle valve for urinal, or with the faucet 01. In the case of faucet, double arrow goes, from toggle valves 80, to the faucet 01, what also means that it could represents double water lines in the case of a faucet for cold and hot water. In the case of angle valve for urinal, single arrow goes from the toggle valve 80 to the spout towards urinal, which represents single water line for cold water. Related to a faucet, during the system working mode which is mixture of the manual and hands free modes, water goes from the wall water network over shut off valves 90, toggle valves 70 compatibly working positioned compared to the toggle valves 80, through control valve of valve assembly 20, which is actually hydraulic switch electrically actuated, further, over toggle valves 80 compatibly positioned related to the toggle valves 70, and finally to the conventional faucet 01. Similarly, related to the angle valve for urinal, during automatic working mode, water goes from the wall water network through the angle valve for urinal, toggle valve 70, control valve of valve assembly 20, toggle valve 80, to the spout towards urinal. Related to faucets, during the system working mode which is mixture of manual and hands free modes, the water parameters of the conventional faucet 01 are adjusted manually, the toggle valves 70 and 80 is correspondingly positioned to allow water way from toggle valves 70 through, control valve of valve assembly 20, to toggle valves 80. Similarly, related to angle valve for urinal, during automatic mode, flow rate through angle valve for urinal is adjusted manually, the toggle valves 70 and 80 is correspondingly positioned to allow water way from toggle valve 70 through, control valve of valve assembly 20, to toggle valve 80. In the case, proximity sensors of sensor assembly 10, which are electrically connected to the control valve of valve assembly 20, over control electronic, detect an object in the detecting zone, like hands in the case of faucet, or a person in the case of pissoir, it causes the control valve to be activated and opened, so, in the case of faucet, water of the adjusted parameters flows out of the conventional faucet 01, and, in the case of pissoir, water of the adjusted flow rate starts flow out of the angle valve 01 under specific logic. Conversely, when proximity sensors of the sensor assembly 10 do not detect any object in its detecting zone, control valve of the valve assembly 20 is deactivated and closed, so, in the case of faucet, water does not flow out of the conventional faucet 01, that is, out of the angle valve for urinal 01, in the case of pissoir. It is understanding that, in the case of faucets, manual adjustment of water parameters of conventional faucet 01, during the mixture mode of the system, is repeatedly done as many times as one likes, and, in the case of pissoir, manual adjustment of flow rate of conventional angle valve for urinal 01, during automatic mode, could be repeatedly done as many times as it is necessary. During alternate, conventional manual mode, water travels from the wall water network over shut-off valves 90, in the case of faucets, and over angle valve for urinal 01, in the case of pissoir, further, in both cases, over toggle valves 70 which are compatibly positioned related to the toggle valves 80, further over toggle valves 80 which are also compatibly positioned related to the toggle valves 70, and finally to the conventional faucet 01 or spout towards pissoir. Obviously, water way of the alternate, conventional manual mode in the case of faucets, that is, conventional mode in the case of pissoir, is bypassed according to the water way of the mixture mode or automatic one, for the reason of the malfunction cases of the valve assembly 20 and sensor assembly 10. The shut-off valves 90 allows for simplified maintenance of the system in the case of faucets. The sensor assembly 10 and valve assembly 20 are, hereinafter discussed in details.

In the present global, general embodiment of the invention, sensor assembly 10, in the case of already existing-installed conventional faucet 01 and conventional angle valve for urinal 01, is a part which is added, combined with them, in the base zone of faucet 01 or somewhere else, for example in the very top of its spout, or is located into sensors assembly and valve assembly housing for pissoir, while in the case of quite new faucets which are almost like conventional ones, sensors assembly is built in it, in its base part or somewhere else e.g. in the very top of its spout. At figures 1 and 2, sensors assembly 10, which is added to the already existing-installed faucet or angle valve for urinal, is indicated by solid line, while that built in quite new conventional faucet, by dashed line. Also, the arrows denoting communication signals between sensors assembly and control electronic, are in solid line in the first case, and in dashed line in the second case. Sensors assembly 10 comprises the actual infrared proximity sensors as known in the state of art or alternatively of some other type, electronic sensor card and electrical cable by means of which sensors and sensor electronic card is operably connected with control electronic as consisting part of valve assembly 20. Electrical cable has double role, the sensors to be power supplied from battery by means of it, and detecting current impulse signal to be sent from sensors to control electronic, through it, which causes the control valve of valve assembly 20 to take one stable state, that is to be opened. Vanishing of an object from the detecting zone of the proximity sensors, also causes an current impulse to be sent from sensors to control electronic, through electrical cable, which causes the control valve of valve assembly 20 to take another stable state, that is to be closed. Specified opening and closing of control valve of valve assembly 20, in the case of pissoir, is realized under specific logic, like, the valve is opened by some delay after a person used urinal go away and the valve is closed after some programmed delay time.

In the present global, general embodiment of the invention, the valve assembly 20 comprises electrically actuated control valve of magnetically latching pilot-controlled solenoid valve type, not commercial, but originally developed for the purpose, control electronic also originally developed for the purpose, and autonomous power supply from commercially available lithium or other battery of 6 or 9 volts. Control valve is single one, in the case of either faucet only for cold water or angle valve for urinal, or double one, in the case of faucet for cold and hot water. Control electronic and battery are located inside the valve assembly housing. The construction of the control valve and control electronic is so that enormously small energy consumption from battery is guaranteed. At stand by regime during any stable state of control valve, when proximity sensors consume energy only, the current is under 10μΑ Current impulses for switching control valve from one to another stable state is of enormously short last of 10÷15m sec and of intensity of 0,3÷0.4A Depending of the total daily circles number whose physical upper bound is approximately around 500, the battery could theoretically lasts from three to five years. Alternatively, instead of battery, internal turbine could be used, which is powered by water everywhen water flows out of the faucet or angle valve for pissoir, and creates an electrical current that is stored in rechargeable cells. The solution is ecological for battery disposal or recycling is avoided.

The first illustrative embodiment concerning the already existing-installed conventional faucet only for cold water used in residential and all other places and circumstances where it is normally to be used. The conventional faucet is upgraded into automatic one by complementing it, that is, adding of control valve in series, and proximity sensors, to be used, nominally in mode which is mixture of manual and automatic hands free modes, and exceptionally, in only manual mode when the automatic system is malfunctioned. The control valve is especially developed for the purpose, with extremely small energy consumption from battery power supply or as alternate any type of solenoid valve could be used with no guarantees the power consumption would be extremely small. By the conventional faucet one adjusts flow and after that uses the water of the adjusted parameter, under hands free principle. Reuse of the faucet possibly means readjust of water flow and further use the water of the readjusted flow. In that way rational consumption of water is guaranteed, that is, only when it is actually used.

Figures 3a) and 3b) show, respectively, a side view and front view of the embodiment of the already existing-installed conventional faucet only for cold water upgraded into automatic one, all generally indicated at 100. The embodiment comprises the conventional faucet only for cold water 101 , the sink 105, the sensor assembly 110, originally developed valve assembly 120, toggle valves 170 and 180, shut-off valve 190 and water lines. Preferably, cold water enters the system from the wall water network through the shut-off valve 190 into the only inlet 171 of the toggle valve 170 and further travels alternatively to the one of the outlets 172 or 173 of the toggle valve 170, depending of its two working positions, which refers to the two working modes of the system, one which is mixture of the manual and hands free modes, and another one which is conventional manual mode. Alternatively, the outlet 172 od the toggle valve 170 is in use during the system mode which is mixture of the manual and hands free modes, and the outlet 173 of the toggle valve 170 is in use during the system conventional manual mode. One of the two working position of the toggle valve 170 is selected manually. The toggle valve 170 is operably connected, to the originally developed single valve assembly 120 by hydraulic line 191 which goes from the outlet 172 of the toggle valve 170 to the inlet 121 of valve assembly 120 over neck 193, and to the toggle valve 180 by hydraulic line 192 which goes from the outlet 173 of the toggle valve 170 to the inlet 182 of the toggle valve 180. Also, the valve assembly 120 is operably connected to the toggle valve 180 by hydraulic line 194 which goes from the outlet 122 of the valve assembly 120 over double neck 195 to the inlet 181 of toggle valve 180. The toggle valve 180 is operably connected to the conventional faucet 101 , over its only outlet 183 directly to the inlet 102 of the conventional faucet 101. During the system working mode which is mixture of manual and hands free modes, water travels from the wall water network over shut-off valve 190, toggle valve 170 which is compatibly positioned related to the toggle valve 180, through hydraulic line 191, through the valve assembly 120 which is actually hydraulic switch electrically controlled, further through hydraulic line 194, further over toggle valve 180 which is also compatibly positioned related to the toggle valve 170, and finally to the conventional faucet. During the system working mode which is mixture of manual and hands free modes, the flow rate of the conventional faucet 101 is adjusted manually, the toggle valves 170 and 180 is correspondingly positioned to allow water way from toggle valve 170 through hydraulic line 191, valve assembly 120, hydraulic line 194 to toggle valve 180. In the case, proximity sensors of sensor assembly 110, which are electrically connected to the control valve of valve assembly 120, over control electronic, detect an object like hands in the detecting zone, it causes the control valve to be activated and opened, so water of the adjusted flow rate flows out of the conventional faucet 101. Conversely, when proximity sensors of the sensor assembly 110 do not detect any object in its detecting zone, control valve of the valve assembly 120 is deactivated and closed, so water does not flow out of the conventional faucet 101. It is understanding that manual 5 adjustment of flow rate of conventional faucet 101, during the mixture mode of the system, is repeatedly done as many times as one likes. During alternate, conventional manual mode, water travels from the wall water network over shut-off valve 190, toggle valve 170 which is compatibly positioned related to the toggle valve 180, through hydraulic line 192, further over toggle valve 180 which is also compatibly positioned related to the toggle valve 170,

10 and finally to the conventional faucet. Obviously, water way of the alternate conventional manual mode is bypassed according to the water way of the mixture mode, for the reason of the malfunction cases of the valve assembly 120 and sensor assembly 110. Shut-off valve 190 allows for simplified maintenance of the system. The sensor assembly 110 and valve assembly 120 are, hereinafter discussed in details.

15 In the present embodiment, sensor assembly 110 is a part which is added, complemented to the already existing-installed conventional faucet 101 in the base zone of it, and comprises the sensors carrier 111, the actual infrared proximity sensors 112 as known in the state of art or alternatively of some other type, electronic sensor card internally located into sensors carrier 111 and electrical cable 113 by means of which sensors and sensor electronic card is

20 operably connected with control electronic as consisting part of valve assembly 120. Electrical cable 113 has double role, the sensors 112 to be power supplied from battery by means of it, and detecting current impulse signal to be sent from sensors to control electronic, through it, which causes the control valve of valve assembly 120 to take one stable state, that is to be opened. Vanishing of an object like hands from the detecting zone of the proximity sensors

25 112, also causes an current impulse to be sent from sensors to control electronic, through electrical cable 113, which causes the control valve of valve assembly 120 to take another stable state, that is to be closed.

Alternatively, in the present embodiment, figures 4a) and 4b) show, respectively, a side view and front view of only faucet and alternate sensor assembly 115 as a part which is

30 added, complemented also to the already existing-installed conventional faucet 101 in the very top of the spout of the faucet, and which comprises the sensor carrier 116, the actual infrared proximity sensors 117 as known in the state of art or alternatively of some other type, electronic sensor card internally located into sensors carrier 116, electrical cable 113 by means of which sensors and sensor electronic card is operably connected with control

35 electronic as consisting part of valve assembly 120, and stainless steel tube 119 which is fixed to the faucet 101 and serve the electrical cable to cross through it. Aerator of the faucet is designed by 118. In the embodiment, the valve assembly 120 comprises electrically actuated single control valve 123 of magnetically latching pilot-controlled solenoid valve type not commercial but originally developed for the purpose, control electronic also originally developed for the purpose, and autonomous power supply from commercially available lithium or other battery of 6 or 9 volts. Control electronic and battery are located inside the valve assembly housing 124. The construction of the control valve and control electronic is so that enormously small energy consumption from battery is guaranteed. At stand by regime during any stable state of control valve, when proximity sensors consume energy only, the current is under ΙΟμΑ. Current impulses for switching control valve from one to another stable state is of enormously short last of 10÷15r/¾ sec and of intensity of 0,3- -0 AA. Depending of the total daily circles number whose physical upper bound is approximately around 500, the battery could theoretically lasts from three to five years.

In another alternative embodiment, instead of battery, internal turbine could be used, which is powered by water everywhen water flows out of the faucet, and creates an electrical current that is stored in rechargeable cells. The solution is ecological for battery disposal or recycling is avoided.

Similarly, the second illustrative embodiment concerning quite new faucets for cold water to be used in residential and all other places and circumstances where it is normally to be used, which are almost, that is, like conventional ones but with small addition, with proximity sensors in the base zone of them or somewhere else built in it, combining with control valve in series, and control electronic all autonomously powered by own battery, into automatic ones. The resulting automatic device is nominally to be used, in mode which is mixture of manual and automatic hands free modes, and exceptionally, in only manual mode when the automatic system is malfunctioned. The control valve is especially developed for the purpose, with extremely small energy consumption from battery power supply or as alternate any type of solenoid valve could be used with no guarantees the power consumption would be extremely small. By the conventional faucet one adjusts flow and after that uses the water of the adjusted parameter, under hands free principle. Reuse of the faucet possibly means readjust of water flow and further use the water of the readjusted flow. In that way rational consumption of water is guaranteed, that is, only when it is actually used.

Figures 5a) and 5b) show, respectively, a side view and front view of the quite new faucet only for cold water which is almost, that is, like conventional one but with small addition, with actual infrared proximity sensors or some other type, in the base zone of it, generally indicated at 500. The faucet comprises the conventional faucet only for cold water 501 , the built in proximity sensors 510, the built in electrical cable for connection of sensors and control electronic 511 , connectors 512. The electronic sensors card is also built in internally but not visible at figures 5a) and 5b) . Further discussion of the sensor assembly, which is, concerning the present embodiment, built in the faucet, is quite the same as it was in the previous embodiment concerning the already existing-installed faucet. Also, discussion of valve assembly concerning the present embodiment is the same as it was in the previous embodiment, as well as discussion related to the possible use of internal turbine and rechargeable cells instead of battery.

Alternatively, in the present embodiment, figures 6a) and 6b) show, respectively, a side view and front view of only faucet 601 but this time with infrared or some other type proximity sensors 610 built in it at the very top of the spout of the faucet. Electronic sensor card is internally located into the faucet as well as electrical cable 611 by means of which sensors and sensor electronic card is operably connected with control electronic over connectors 612.

The third illustrative embodiment concerning the already existing-installed conventional faucet for cold and hot water to be mixed, either with only one handle or with two handles, used in residential and all other places and circumstances where it is normally to be used. The conventional faucet is upgraded into automatic one by complementing it, that is, adding of control valve in series, and proximity sensors, to be used, nominally in mode which is mixture of manual and automatic hands free modes, and exceptionally, in only manual mode when the automatic system is malfunctioned. The control valve is especially developed for the purpose, with extremely small energy consumption from battery power supply or as alternate any type of solenoid valve could be used with no guarantees the power consumption would be extremely small. By the conventional faucet one adjusts flow and temperature and after that uses the water of the adjusted parameter, under hands free principle. Reuse of the faucet possibly means readjust of water flow and/or temperature and further use the water of the readjusted flow and/or temperature. In that way rational consumption of water and energy is guaranteed, that is, only when it is actually used.

Figures 7a) and 7b) show, respectively, a side view and front view of the embodiment of the already existing-installed conventional faucet for cold and hot water to be mixed, with only one handle, upgraded into automatic one, all generally indicated at 200. The embodiment comprises the conventional faucet for cold and hot water to be mixed, with only one handle, 201, the sink 206, the sensor assembly 210, originally developed valve assembly 220, toggle valves 270, 275, 280 and 285, shut-off valve 288 and 289 and water lines. Preferably, cold water enters the system from the wall water network through the shut-off valve 288 into the only inlet 271 of the toggle valve 270 and further travels alternatively to the one of the outlets 272 or 273 of the toggle valve 270, depending of its two working positions, which refers to the two working modes of the system, one which is mixture of the manual and hands free modes, and another one which is conventional manual mode. Alternatively, the outlet 272 od the toggle valve 270 is in use during the system mode which is mixture of the manual and hands free modes, and the outlet 273 of the toggle valve 270 is in use during the system conventional manual mode. One of the two working positions of the toggle valve 270 is selected manually. The toggle valve 270 is operably connected, to the originally developed double valve assembly 220 by hydraulic line 290 which goes from the outlet 272 of the toggle valve 270 to the inlet 221 of valve assembly 220 over neck 292, and to the toggle valve 280 by hydraulic line 291 which goes from the outlet 273 of the toggle valve 270 to the inlet 282 of the toggle valve 280. Also, the valve assembly 220 is operably connected to the toggle valve 280 by hydraulic line 293 which goes from the outlet 222 of the valve assembly 220 over double neck 294 to the inlet 281 of toggle valve 280. The toggle valve 280 is operably connected to the conventional faucet 201, over its only outlet 283 to the inlet line 202 of the conventional faucet 201 over double nipple 203. Similarly, hot water enters the system also from the wall water network through the shut-off valve 289 into the only inlet 276 of the toggle valve 275 and further travels alternatively to the one of the outlets 277 or 278 of the toggle valve 275, depending of its two working positions, which refers to the two working modes of the system, one which is mixture of the manual and hands free modes, and another one which is conventional manual mode. Alternatively, the outlet 277 od the toggle valve 275 is in use during the system mode which is mixture of the manual and hands free modes, and the outlet 278 of the toggle valve 275 is in use during the system conventional manual mode. One of the two working positions of the toggle valve 275 is selected manually. The toggle valve 275 is operably connected, to the originally developed double valve assembly 220 by hydraulic line 295 which goes from the outlet 277 of the toggle valve 275 to the inlet 223 of valve assembly 220 over neck 297, and to the toggle valve 285 by hydraulic line 296 which goes from the outlet 278 of the toggle valve 275 to the inlet 287 of the toggle valve 285. Also, the valve assembly 220 is operably connected to the toggle valve 285 by hydraulic line 298 which goes from the outlet 224 of the valve assembly 220 over double neck 299 to the inlet 286 of toggle valve 285. The toggle valve 285 is operably connected to the conventional faucet 201 , over its only outlet 284 to the inlet line 204 of the conventional faucet 201 over double nipple 205. During the system working mode which is mixture of manual and hands free modes, cold water travels from the wall water network over shut-off valve 288, toggle valve 270 which is compatibly positioned related to the toggle valve 280, through hydraulic line 290, through the valve assembly 220 which is actually hydraulic switch electrically controlled, further through hydraulic line 293, further over toggle valve 280 which is also compatibly positioned related to the toggle valve 270, and finally throughout inlet line 202 of the conventional faucet to the conventional faucet. Similarly, during the system working mode which is mixture of manual and hands free modes, hot water travels from the wall water network over shut-off valve 289, toggle valve 275 which is compatibly positioned related to the toggle valve 285, through hydraulic line 295, through the valve assembly 220 which is actually hydraulic switch electrically controlled, further through hydraulic line 298, further over toggle valve 285 which is also compatibly positioned related to the toggle valve 275, and finally throughout inlet line 204 of the conventional faucet to the conventional faucet. During the system working mode which is mixture of manual and hands free modes, the flow rate and water temperature of the conventional faucet 201 is adjusted manually, the pairs of the toggle valves 270, 280 and 275, 285 are correspondingly positioned to allow, cold water way from toggle valve 270 through hydraulic line 290, valve assembly 220, hydraulic line 293 to toggle valve 280, and hot water way from toggle valve 275 through hydraulic line 295, valve assembly 220, hydraulic line 298 to toggle valve 285. In the case, proximity sensors of sensor assembly 210, which are electrically connected to the control valve of valve assembly 220, over control electronic, detect an object like hands in the detecting zone, it causes the control valve to be activated and opened, so water of the adjusted flow rate and temperature flows out of the conventional faucet 201. Conversely, when proximity sensors of the sensor assembly 210 do not detect any object in its detecting zone, control valve of the valve assembly 220 is deactivated and closed, so water does not flow out of the conventional faucet 201. It is understanding that manual adjustment of flow rate and temperature of conventional faucet 201, during the mixture mode of the system, is repeatedly done as many times as one likes. During alternate, conventional manual mode, cold water travels from the wall water network over shut-off valve 288, toggle valve 270 which is compatibly positioned related to the toggle valve 280, through hydraulic line 291, further over toggle valve 280 which is also compatibly positioned related to the toggle valve 270, and finally to the conventional faucet, and hot water travels from the wall network over shut-off vale 289, toggle valve 275 which is compatibly positioned related to the toggle valve 285, through hydraulic line 296, further over toggle valve 285 which is also compatibly positioned related to the toggle valve 275, and finally to the conventional faucet. Obviously, water way of the alternate conventional manual mode is bypassed according to the water way of the mixture mode, for the reason of the malfunction cases¾pf the valve assembly 220 and sensor assembly 210. Shut-off valves 288 and 289 allow for simplified maintenance of the system. The sensor assembly 210 and valve assembly 220 are, hereinafter discussed in details.

In the present embodiment, sensor assembly 210 is aj part which is added, complemented to the already existing-installed conventional faucet 2,01 in the base zone of it, and comprises the sensors carrier 211, the actual infrared proximity sensors 212 as known in the state of art, electronic sensor card internally located into sensors carrier 211 and electrical cable 213 by means of which sensors and sensor electronic card is operably connected with control electronic as consisting part of valve assembly 220. Electrical cable 213 has double role, the sensors 212 to be power supplied from battery by means of it, and detecting current impulse signal to be sent from sensors to control electronic, through it, which causes the control valve of valve assembly 220 to take one stable state, that is to be opened. Vanishing of an object like hands from the detecting zone of the proximity sensors 212, also causes an current impulse to be sent from sensors to control electronic, through electrical cable 213, which causes the control valve of valve assembly 220 to take another stable state, that is to be closed.

Alternatively, in the present embodiment, figures 8a) and 8b) show, respectively, a side view and front view of only faucet and alternate sensor assembly 215 as a part which is added, complemented also to the already existing-installed conventional faucet 201 in the very top of the spout of the faucet, and which comprises the sensor carrier 216, the actual infrared proximity sensors 217 as known in the state of art or alternatively of some other type, electronic sensor card internally located into sensors carrier 216, electrical cable 213 by means of which sensors and sensor electronic card is operably connected with control electronic as consisting part of valve assembly 220, and stainless steel tube 219 which is fixed to the faucet 201 and serve the electrical cable to cross through it. Aerator of the faucet is designed by 218.

In the embodiment the valve assembly 220 comprises electrically actuated double control valve 225 of magnetically latching pilot-controlled solenoid valve type not commercial but originally developed for the purpose, control electronic also originally developed for the purpose, and autonomous power supply from commercially available lithium or other battery of 6 or 9 volts. Control electronic and battery are located inside the valve assembly housing 226. The construction of the control valve and control electronic is so that enormously small energy consumption from battery is guaranteed. At stand by regime during any stable state of control valve, when proximity sensors consume energy only, the current is under 10μΑ. Current impulses for switching control valve from one to another stable state is of enormously short last of 10÷15m sec and of intensity of 0,3÷0.4A Depending of the total daily circles number whose physical upper bound is approximately around 500, the battery could theoretically lasts from three to five years.

In another, alternative embodiment, instead of battery, internal turbine could be used, which is powered by water every when water flows out of the faucet, and creates an electrical current that is stored in rechargeable cells. The solution is ecological for battery disposal or recycling i¾ avoided.

Similarly, the fourth illustrative embodiment concerning quite new faucets for cold and hot water to be mixed, either with only one handle or with two handles, to be used in residential and all other places and circumstances where it is normally used, which are almost, that is, like conventional ones but with small addition, with proximity sensors in the base zone of them, combining with control valve in series, and control electronic all autonomously powered by own battery, into automatic ones. The resulting automatic device is nominally to be used, in mode which is mixture of manual and automatic hands free modes, and exceptionally, in only manual mode when the automatic system is malfunctioned. The control valve is especially developed for the purpose, with extremely small energy consumption from battery power supply or as alternate any type of solenoid valve could be used with no guar- antees the power consumption would be extremely small. By the conventional faucet one adjusts flow and after that uses the water of the adjusted parameter, under hands free principle. Reuse of the faucet possibly means readjust of water flow and further use the water of the readjusted flow. In that way rational consumption of water is guaranteed, that is, only when it is actually used.

Figures 9a) and 9b) show, respectively, a side view and front view of the quite new faucet for cold and hot water to be mixed, which is almost, that is, like conventional one but with small addition, with actual infrared proximity sensors in the base zone of it built in, generally indicated at 700. The faucet comprises the conventional faucet for cold and hot water to be mixed 701, the built in proximity sensors 710, the built in electrical cable for connection of sensors and control electronic 711, connectors 712. The electronic sensors card is also built in internally but not visible at figures 9a) and 9b). Further discussion of the sensor assembly, which is, concerning the present embodiment, built in the faucet, is quite the same as it was in the previous embodiment concerning the already existing-installed faucet. Also, discussion of valve assembly concerning the present embodiment is the same as it was in the previous embodiment, as well as discussion related to the possible use of internal turbine and rechargeable cells instead of battery.

Alternatively, in the present embodiment, figures 10a) and 10b) show, respectively, a side view and front view of only faucet 801 but this time with infrared or some other type proximity sensors 810 built in it at the very top of the spout of the faucet. Electronic sensor card is internally located into the faucet as well as electrical cable 811 by means of which sensors and sensor electronic card is operably connected with control electronic over connectors 812.

The fifth illustrative embodiment concerning the already existing-installed conventional faucet for cold and hot water to be mixed, either with only one handle or with two handles, used especially in kitchen circumstances, in residential and all other places where it is normally to be used. The conventional faucet is upgraded into automatic one by complementing it, that is, adding of control valve in series, and proximity sensors, to be used, nominally in mode which is mixture of manual and automatic hands free modes, and exceptionally, in only manual mode when the automatic system is malfunctioned. The control valve is es- pecially developed for the purpose, with extremely small energy consumption from battery power supply or ..as alternate any type of solenoid valve could be used with no guarantees the power consumption would be extremely small. By the conventional faucet one adjusts flow and temperature and after that uses the water of the adjusted parameters, under hands free principle. Reuse of the faucet possibly means readjust of water flow and/or temperature and further use the water of the readjusted flow and/or temperature. In that way rational consumption of water and energy is guaranteed, that is, only when it is actually used. 5 Figures 11a) and lib) show, respectively, a side view and front view of the embodiment of the already existing-installed conventional faucet for cold and hot water to be mixed, with only one handle, preferably used in kitchen circumstances, upgraded into automatic one, all generally indicated at 300.

As the explanation of the system, in details, is quite compatible to the explanation already done related to the figures 7a) and 7b) , it will not be again repeated.

As, in the present embodiment, sensor assembly 310 and valve assembly 320 is quite

15 compatible to the sensor assembly 210 and valve assembly 220 of the previous embodiment, detailed explanation from the previous embodiment is valid here too, and it is not repeated again for the clear reason. In the present embodiment, the sensors carrier is designated by 311, the actual infrared proximity sensors by 312, electrical cable by 313, double control valve by 325 and valve assembly housing by 326.

20 Alternatively, in the present embodiment, figures 12a) and 12b) show, respectively, a side view and front view of only faucet and alternate sensor assembly 315 as a part which is added, complemented also to the already existing-installed conventional faucet 301 in the very top of the spout of the faucet, and which comprises the sensor carrier 316, the actual infrared proximity sensors 317 as known in the state of art or alternatively of some other

25 type, electronic sensor card internally located into sensors carrier 316, electrical cable 313 by means of which sensors and sensor electronic card is operably connected with control electronic as consisting part of valve assembly 320, and stainless steel tube 319 which is fixed to the faucet 301 and serve the electrical cable to cross through it. Aerator of the faucet is designed by 318.

30 Similarly, the sixth illustrative embodiment concerning quite new faucets for cold and hot water to be mixed, either with only one handle or with two handles, to be used especially in kitchen circumstances, in residential and all other places where it is normally used, which are almost, that is, like conventional ones but with small addition, with proximity sensors in the base zone of them built in, combining with control valve in series, and control

35 electronic all autonomously powered by own battery, into automatic ones. The resulting automatic device is nominally to be used, in mode which is mixture of manual and automatic hands free modes, and exceptionally, in only manual mode when the automatic system is malfunctioned. The control valve is especially developed for the purpose, with extremely small energy consumption from battery power supply or as alternate any type of solenoid valve could be used with no guarantees the power consumption would be extremely small. By the conventional faucet one adjusts flow and after that uses the water of the adjusted parameter, under hands free principle. Reuse of the faucet possibly means readjust of water flow and further use the water of the readjusted flow. In that way rational consumption of water is guaranteed, that is, only when it is actually used.

Figures 13a) and 13b) show, respectively, a side view and front view of the quite new faucet for cold and hot water to be mixed, with only one handle, to be used especially in kitchen circumstances, which is almost, that is, like conventional one but with small addition, with actual infrared proximity sensors in the base zone of it built in, generally indicated at 900. The faucet comprises the conventional faucet for cold and hot water to be mixed 901, the built in proximity sensors 910, the built in electrical cable for connection of sensors and control electronic 911, connectors 912. The electronic sensors card is also built in internally but not visible at figures 13a) and 13b). Further discussion of the sensor assembly, which is, concerning the present embodiment, built in the faucet, is quite the same as it was in the previous embodiment concerning the already existing-installed faucet. Also, discussion of valve assembly concerning the present embodiment is the same as it was in the previous embodiment, as well as discussion related to the possible use of internal turbine and rechargeable cells instead of battery.

Alternatively, in the present embodiment, figures 14a) and 14b) show, respectively, a side view and front view of only faucet 1001 but this time with infrared or some other type proximity sensors 1010 built in it at the very top of the spout of the faucet. Electronic sensor card is internally located into the faucet as well as electrical cable 1011 by means of which sensors and sensor electronic card is operably connected with control electronic over connectors 1012.

The seventh illustrative embodiment concerning the already existing-installed conventional angle valve for urinal used in public and all other places and circumstances where it is normally to be used. The conventional angle valve is upgraded into automatic one by complementing it, that is, adding of control valve in series, and proximity sensors, to be used, nominally in automatic mode, and exceptionally, in conventional mode when the automatic system is malfunctioned. The control valve is especially developed for the purpose, with extremely small energy consumption from battery power supply or as alternate any type of solenoid valve could be used with no guarantees the power consumption would be extremely small. By the conventional angle valve for urinal water flow is adjusted in advance and after that the urinal is used with the adjusted water flow, under automatic regime. If necessary the water flow could be possibly readjusted by conventional angle valve for urinal again. Urinal automatic working regime is under specific logic achieved through control electronic. In that way rational consumption of water is guaranteed, that is, only when urinal is actually used.

Figures 15a) and 15b) show, respectively, a side view and front view of the embodiment of the already existing-installed conventional angle valve for urinal upgraded into automatic one, all generally indicated at 400. The embodiment comprises the conventional angle valve for urinal, 401, the urinal 405, the sensor assembly 410, originally developed valve assembly 420, toggle valves 470 and 480 and water lines. Preferably, cold water enters the system from the wall water network through the angle valve for urinal 401 into the only inlet 471 of the toggle valve 470 and further travels alternatively to the one of the outlets 472 or 473 of the toggle valve 470, depending of its two working positions, which refers to the two working modes of the system, one which is automatic, and another one which is conventional mode. Alternatively, the outlet 472 od the toggle valve 470 is in use during the automatic system mode, and the outlet 473 of the toggle valve 470 is in use during the system conventional mode. One of the two working position of the toggle valve 470 is selected manually. The toggle valve 470 is operably connected, to the originally developed single valve assembly 420, directly from the outlet 472 of the toggle valve 470 to the inlet 421 of valve assembly 420 over neck 490, and to the toggle valve 480 by hydraulic line 491 which goes from the outlet 473 of the toggle valve 470 to the inlet 482 of the toggle valve 480. Also, the valve assembly 420 is operably connected to the toggle valve 480, directly from the outlet 422 of the valve assembly 420 over double neck 492 to the inlet 481 of toggle valve 480. The toggle valve 480 is operably connected to the urinal 405, over its only outlet 483 directly by hydraulic line 493. During the system automatic working mode, water travels from the wall water network through the angle valve for urinal 401 , toggle valve 470 which is compatibly positioned related to the toggle valve 480, through the valve assembly 420 which is actually hydraulic switch electrically controlled, further through toggle valve 480 which is also compatibly positioned related to the toggle valve 470, and finally through hydraulic line 493 to the urinal. During the system automatic working mode, the flow rate of the conventional angle valve for urinal 401 is adjusted manually, the toggle valves 470 and 480 is correspondingly positioned to allow water way from toggle valve 470 through valve assembly 420 to toggle valve 480. In the case, proximity sensors of sensor assembly 410, which are electrically connected to the control valve of valve assembly 420, over control electronic, detect an object (person) in the detecting zone, it causes the control valve to be activated and opened, so water of the adjusted flow rate flows out of the conventional angle valve 401 under the specific logic. Conversely, when proximity sensors of the sensor assembly 410 do not detect any object (person) in its detecting zone, control valve of the valve assembly 420 is deactivated and closed, so water does not flow out of the conventional angle valve for urinal 401. It is understanding that manual adjustment of flow rate of conventional angle valve for urinal 401, during the automatic working mode of the system, is repeatedly done as many times as it is necessary. During alternate, conventional mode, water travels from the wall water network through the angle valve for urinal 401 , toggle valve 470 which is compatibly positioned related to the toggle valve 480, through hydraulic line 491 , further over toggle valve 480 which is also compatibly positioned related to the toggle valve 470, and finally through hydraulic line 493 to the urinal. Obviously, water way of the alternate conventional mode is bypassed according to the water way of the automatic mode, for the reason of the malfunction cases of the valve assembly 420 and sensor assembly 410. The angle valve for urinal 401 allows for simplified maintenance of the system. The sensor assembly 410 and valve assembly 420 are, hereinafter discussed in details.

In the present embodiment, sensor assembly 410 comprises the actual infrared proximity sensors 411 as known in the state of art, electronic sensor card internally located into sensors assembly and valve assembly housing 424 and electrical cable by means of which sensors and sensor electronic card is operably connected with control electronic as consisting part of valve assembly 420, also internally located into sensors assembly and valve assembly housing 424 as well as battery power supply. Internal sensor assembly electrical cable has double role, the sensors 411 to be power supplied from battery by means of it, and detecting current impulse signal to be sent from sensors to control electronic, through it, as well as also current impulse caused by vanish of an object like person from the detecting zone of the proximity sensors 411 , which both cause the control valve of valve assembly 420 to take one stable state, that is to be opened and another stable state, that is to be closed, but under specific logic, like, the valve is opened by some delay after a person go away and the valve is closed after some programmed delay time.

In the embodiment the valve assembly 420 comprises electrically actuated single control valve 423 of magnetically latching pilot-controlled solenoid valve type not commercial but originally developed for the purpose, control electronic also originally developed for the purpose, and autonomous power supply from commercially available lithium or other battery of 6 or 9 volts. Control electronic and battery are located inside the sensor assembly and valve assembly housing 424. The construction of the control valve and control electronic is so that enormously small energy consumption from battery is guaranteed. At stand by regime during any stable state of control valve, when proximity sensors consume energy only, the current is under 10 Α Current impulses for switching control valve from one to another stable state is of enormously short last of 10÷15m sec and of intensity of 0,3÷0.4A Depending of the total daily circles number whose physical upper bound is approximately around 500, the battery could theoretically lasts from three to five years.

In another alternative embodiment, instead of battery, internal turbine could be used, which is powered by water every when water flows out of the faucet, and creates an electrical current that is stored in rechargeable cells. The solution is ecological for battery disposal or recycling is avoided.
