| CLAIMS Water saving device 1. Water saving device which consists of two valves, input (E), output (ξ), a fin (φ), a series of toothed wheels (PI, l ~ 2, l ~ 3, T4, l " 5), which function as a reduction gear, two separate toothed wheels (out of the reduction gear), disconnection gear (A) and immediate disconnection gear (B). The device also has levers, springs and two control levers (M1, M2). The above mentioned parts work together in order to close the output valve (ξ), which is activated by the (A) gear or the (B) gear, in case of unwise water consumption. 2. Water saving device which, as mentioned in Claim 1, includes amongst the other parts, an input valve (E), which, with the slightest water flow, activates lever (X2) and then lever (X3), which bears the disconnection gear (A), which by opening valve (E) shifts and touches the toothed wheel of the axis toothed wheel (l ~ 5), which is already rotating, because the fin (φ) spins as the water flows, thus rotating the toothed wheels (l ~ 1 , V2, l ~ 3, YA, T 1 S), since it is bearing a toothed wheel on its axis. Inside the disconnection gear (A) there is a drum inside which there is a spiral spring (λ1), which brings back gear (A) to its initial position (as far as its rotation is concerned) when the input valve (E) switches off and stops from being adjacent to the axis of the toothed wheel (F5). The disconnection gear (A) bears a spring (λ1) to bring back its rotation, while the immediate disconnection gear (B) bears a counterweight (N) to bring it back. Water saving device, which - as mentioned in Claim 1 - cuts off the water in case of unwise consumption by closing down the output valve (ξ), which is activated by the disconnection gear (A) 1 or the immediate disconnection gear (B). When the water is cut off, the consumer may restore the flow by turning the control lever (M 1), which bears a cam (K2), which pushes lever (M5), which in its turn bears a hook (M4), which is then hooked to the fixed point (σ). |
DESCRIPTION Water saving device The invention refers to a water saving device.
The device may be used in any water supply installation. It has the possibility of cutting off the water supply, in case the user is unnecessarily consuming water or in case of damaged installations.
The device is placed on the water supply installations, after the hydrometer. From the moment there is an uncontrolled water flow, for any reason whatsoever, the water is automatically cut off. Therefore, the user should not let the tap open, thus making unnecessary consumption. Consequently, he should be closing the tap at times provided he is consuming water. Also, in case of damage of the installations the water is automatically cut off. The water comes back after the user intervenes on the device by turning a small lever (M1).
The device may be placed in larger installations (in the proper size), e.g. dams or irrigation works.
When hotels are concerned a device properly adjusted should be installed in each room or apartment. We ought to say that approximately 20liters of water must go through so that the device may function and carry out the cut off. This makes it possible for a laundry machine to function as it needs about this quantity to operate at the same time with 2 taps, e.g. kitchen, toilet, bath-tub. We certainly have the possibility of cutting off the water during our absence from home by turning a small lever found on the device, immediately after a minimum quantity of water has gone through.
The device is described as economizing, because we save water by turning off the tap at times, while it is at the same time ensuring security, since the water is automatically cut off if the installations suffer damage in the case of our absence.
According to the invention, the device consists of two input (E) and output (ξ) valves, a fin (φ), a series of toothed wheels (Pl, T2, l ~ 3, P4, l~5) which function as a reduction gear, two separate disconnection gears (outside the reduction gear), disconnection gear (A) and of immediate disconnection (B), which activate the output valve (ξ). It also has levers, springs and two control levers (M1, M2).
The device functions as follows: by opening the tap or in case of damage at the installations, the input valve (E) opens, which in turn shifts the disconnection gear (A) to the left with the lever (X1) so that it may be adjacent to the axis of the reduction gear's last toothed wheel (P5), whose toothed wheels rotate with
the help of the fin (φ). There is a cam on the shifted toothed wheel (A) which releases hook (M4) when it turns from the fixed point (σ). When the hook (M4) is released, then the spring (λ2) is exerting pressure, thus closing the output valve (ξ) and as a result the water supply is cut off.
The water cut off takes place as long as we let the tap open for quite some time.
In order to restore the water cut off, we turn lever (M1) by effecting a complete rotation and together with cam (K2) pushes lever (M5), which in turn helps the hook (M4) to hook itself on the fixed point (σ). In this way, the output valve (≡) opens. A void (O) is created simultaneously so that the lever (M5) may move and close the output valve (ξ), should we exceed the allowed quantity of water. If the rotation is not complete but half-way, then we block the output valve (ξ) and as a result the water flow is uninterrupted, provided we want this. However, we ought to avoid this move (half turn) so that there may not be any interlocking in the device.
There is of course the possibility of deactivating the disconnection gear (A), the hook (M4) and the lever (M5), and as a result the output valve (ξ) will remain constantly open. However, in order to save water we should make it a habit to always keep the device in operation.
If we close the tap the input valve (E) closes too and as a result the toothed wheel (A) which has shifted from the same valve and has turned, has returned to its initial position and its rotation has been annihilated with the help of spring (λ1), which is spiral and is found on a drum on the disconnection gear (A). There is a second immediate disconnection gear (B), which is moving downwards with control lever (M2) adjacent to the axis of the second toothed wheel (P2) of the reduction gear and through its rotation with its cam shifts lever (M6), which in its turn unhooks hook (M4) from the fixed point (σ), so as to cut the water as soon as a very small quantity of water passes through during our absence.
When we have activated the immediate disconnection gear (B) and there the water is cut off, then in order to bring the water back we should first bring back the toothed wheel (B) to its initial position with lever (M2) and so its rotation is annihilated with a counterweight (N) found in its perimeter. Afterwards, we turn lever (M 1) completely so that with its cam (K2) it may shift lever (M5), which will then help hook (M4) to be hooked on the fixed point (σ), so as to keep the output valve (ξ) open.
The spring (A3) helps slightly the input valve (E) to remain closed, while spring (λ4) helps the elasticity of the valve itself. A specialized technician will be able to move the cams (K3) of the immediate disconnection gear (B) and of the disconnection gear (A) so as to increase or reduce the quantity of water before cutting it off.
