[Background Art]

Generally the place where the power is needed including cars and industrial facilities uses fossil fuels to produce a power. Power generator for fossil fuels is to obtain a power from combustion of fossil fuels. The general examples are an internal-combustion engine and an external-combustion engine. However, as mentioned above to generate a power by burning fossil fuels a lot of problems come out.

For example, in the above device of power generator to make a power it has to be kept using fossil fuels so it causes to the lack of natural resources or the exhaustion of resources. Also, all sorts of harmful gases by flaming out fossil fuels causing environmental air pollution and become the main factors of the global warming.

Therefore, recently wiLh no use or self-control of fossil fuel, the technology to generate a power is actively being developed. The typical example is the

<The construction of the invention and the operating example>

The invention is made to solve out the problems as mentioned above.

The device, as described in the upper part, has a lot of major parts, namely the storing tank to save lhe fluid, the pressure generating par! to boost the fluid supplied through the saving tank and the first pipeline of supply, the first pumping part which is installed in the storing tank to supply the kinetic energy to move the fluid from the storing tank to the pressure generating part, the power generating part supplied with the boosted fluid from the pressure generating part, the second pumping part, which is connected with the pow er generating part, to supply the fluid in the storing tank with the pressure

generating part from the power in the power generating part, returning pipeline connected with the pressure generating part and the power generating parl to make that the fluid in the pressure generating part gets back to the storing tank through the power generating part, the second supply pipeline connected with the storing tank, the second pumping part, and the pressure generating part to make the fluid in the storing tank move to the pressure generating part through the second pumping part.

The invention as characterized above can be accurately explained with the reasonable operating example.

More detailed explanations will be given below using the reasonable example of the invention based on the inserted drawings.

The Fig. 1 is the rough constituent drawing to show the reasonable example, the Fig. 2 is a drawing to show a producing part of the pressure in the Fig. 1 and the Fig. H is a drawing to show that the power generating part isconnected with the second pumping part.

Λs shown in the Fig.s 1 , 2 and 3 the Hydraulic Power Generating System( lOO) on the invention is divided into the storing tank(l θ), the pressure generating part(3ϋ), the first pumping partCl l), the pow er generating part(bϋ) and the second pumping part(70).

The storing tank has a constant space inside to save the fluid.

The pressure generating part(30) to be supplied with thefluid from the storing tank( lθ) to boost is connected with the storing tank( lθ)

through the first supply pipelined 5). With more detailed description the pressure generating part(3ϋ) is composed of the boosting tank(35), the supply flange(31 ) and the distributing casket so the supply flange(31 ) shows that the One side is connected with the first supply pipeline! 15) and in The other side the penetrating hall(31 a) is formed.

Also, the penetrating hall(31 a) which is connected w ith the distributing casket(31 a) makes that the supply flange(31) is combined with the boosting tank(35) by pipe. In here, it is reasonable to be composed of more than two distributing caskets(33) which combine with the penetrating hall(31 a) to make that the fluid is divided into the multi-channels to provide to the boosting tank(35).

Additionally it is desirable that the checking valve(33a) is installed in the distributing casket(33) to protect the fluid flowing backw ards by the pressure of the boosting tank(35).

The first pumping part(l l) is installed in the storing tank(lθ) to make the fluid move from the storing tank(lθ) to the pressure generating part by putting in the kinetic energy. For the first pumping part( l l) the motor pump driven by electricity can be generally adopted.

The power generating part which is to produce the power supplied with the boosted fluid from the pressure generating part(30) includes a driving method(53) and a driving axle(55). A driving method(53) is to the revolution driving by the fluid pressure so as a driving method(53) the fluid pressure-motor can generally be adopted to be used. The driving axles(55) is connected with the axis of rotationCnot in the figure) of the driving method.

_

Thus, when the axis of rotation of the driving method(53) is rotating it is also possible that the driving axles(55) is rotating. The axis of rotation is connected with the driving axles(55) by couple ring. Also, it is reasonable that the driving axles(5f)) is connected with the wheel. That means regardless of producing the power to make the turning power of the driving axlcs(55) keep steady.

The second pumping(70) includes drive arbor(71 ) and the pumping method(73). The drive arbor(71) is connected with the driving axles(55) of the power generating parl(GO) to be rotated together. The pumping method(73) supported by the rotating power of drive arbor(71) is to pump the fluid of the storing tank(lθ). For the pumping mcthod(73) the piston pump of the fluid pressure can be adopted to be used, and the fully(55a,71a) and the belt(60) for the connection between the drive arbor(71) and the driving axles(δδ) can be adopted for the usage. In other words, the driving axles(55) in the power generating part(50) and the second pumping part(70) in the drive arbor(71 ) each are combined with the pulley(55a,71 a) and to combine the pulley(55a, 71 a) with the belt(6ϋ) it is possible that the driving axles(55) is connected with the drive arbor(71) to be delivered for the power. In here, to take the transmission of the excess of power from the driving axlesC55) to the drive arbor(71 ) it is very difficult to use the power of the driving axles(55). Reversely if it is not enough to have the power a drive on the second pumping part(70) is very hard. Thus, it is reasonable to transmit the suitable power from the driving axles(55) to the drive arbor (71 ) so the power is controlled by the number and the height of the pulley(55a, 71a) and the belt(60) which are connected with the driving axles(55) and the drive arbor(71). Therefore, the second pumping part(7ϋ) is connected with the power generating part(5ϋ) to make it possible that with the power from the power generating

part(GO) the fluid in the storing tank(lθ) is supplied for the pressure generating part (30).

Besides, the power transmitting part(77)is installed in the second pumping prat(70) and the power transmitting part(77) obtains the power from the power generating part(50) to give a permission to use to another driving organ. That is to say, the power generating part(50), if necessary, is connected with another driving organ to use.

For that the power transmitting part(77) combines with the drive arbor in the second pumping part(70). Here, the power transmitting part(77) can be connected with the another axle(not in the figurc)which combines with the driving axlos(55) and belt, and so on. In other words, the power transmitting part(77), even if not connected with the drive arbor(71), which is only combined with the driving axles(55) by power can be operated.

From now in the example the explanation about the pipelines each where the fluid moves around will be given.

From the example the route where the fluid moves around is composed of the first supply pipelined 5), the second supply pipeline(75), the returning pipcline(Hϋ) and a decompression pipeline(85).

The first supply pipeline(15) is the route where the pumped fluid by the first pumping parl(l l ) moves from the storing tankO O) Lo the pressure generating part(30), and the second supply pipeline(75) is the route where the pumped fluid by the second pumping part(7ϋ) moves from the storing tank(l θ) to the pressure generating parl(3ϋ).

That is, the first and second supply pipclines( 15, 75) all are the routes where the fluid is moved from the storing tank(lθ) to the pressure generating part(30).

Therefore, in the first and second supply pipelincs(15, 75) it is reasonable to install the checking valvesClB, 76) to protect the fluid flowing backw ards from lhe pressure in the pressure generating part(3ϋ). On the other hand, the returning pipeline is the route to make the fluid which moves to the pressure generating part(30) through the first and second supply pipclines( 15, 75) going back to the storing tank (10) via the power generating part(50). Thus, the returning pipeline(BO) is connected with the pressure generating part(30), the power generating part(50) and the storing tank(lθ). At this time the fluid to move through the returning pipeline(8ϋ) is used in the power generating μart(50) so it should be moved with the constant boosting pressure.

On the returning pipeline(BO) it is reasonable that the valve(Hl) which is , for example, the checking valve is installed to be open wilh only more than the constant pressure.

Besides, the decompression pipeline(85) is for controlling the pressure in the pressure generating part(3ϋ).

It is possible that the boosting tank(35) on the pressure generating part(3ϋ) combines with the storing tank(lϋ), which makes the fluid on the boosting tank(35) move to the storing tank( l θ) directly.

Here, the moving of the fluid through the decompression pipeline(85), and the flux are intermitted and controlled. On the fluid moving route of the boosting tank(35) and the storing tank(lθ) it is desirable to install the pressure controlling valve(86), and also, it is desired that the pressure gauge(35a) is installed in the boosting tank(35) to measure the internal pressure.

_

From now, as scon in the organization and the structure above, the operation and the principal of the desirable example for the invention will be explained. First of all, to make the fluid in the storing tank( l θ) operate the first pumping part(l l) by the external electricity the fluid is moved from the storing tank(lθ) to the supply flange(31) of the pressure generating part(3ϋ) Io be filled in the boosting tank(35) inside. By the continuous supply of the fluid for the pressure of the boosting tank(35) to be more than the constant pressure the checking valve(Bl) on the returning pipeline(8ϋ) is opened for the fluid to turn the driving method(53) of the power generating part(50) to be back to the storing tank( lθ) again. At this moment for the driving axles(Oυ) to turn by the driving method(53) the drive arbor(71) of the second pumping part(70) which is connected with the driving axles(5r>) is also turning around. By the turn of the drive arbor(71) to drive the pumping method(73) of the second pumping part(7ϋ) the fluid of the storing tank(lϋ) is continuously provided to the pressure generating part(3ϋ) through the second supply pipeline(75).

Moreover, the wheel connected with the driving axles(55) to interrupt supplying the pressure generating part(30) with the fluid to stop the driving method(53) of the power generating part(!50), by the law of inertia, temporarily keeps the pressure to drive the pressure generating part(30) and the power generating parl(GO)

If by the damage of the power from the long time operation the pressure of the pressure generating part(30) is not reached to the allowable pressure(the fluid pressure required to operate the Hydraulic Power Generating System ), by the external power it is natural that the first pumping part( l l ) should be at work. However, the Hydraulic Power Generating vSystem( lOO)

invented by the above principle makes it able to minimize the damage of the pow er.
