The closing of contact switch 123 will open solenoid valve 127. The opening of solenoid valve 127 allows fluid in the upper chamber 128 of hydraulic cylinder 127 to flow through conduit 129 to the lower chamber 130 below piston 131. The movement of hydraulic fluid from upper chamber 128 to lower chamber 130 repositions the piston 132 upward thereby increasing the distance between pin 37 and cross pin 77 of interecting crosshead 34. When secondary lever 26 has been repositioned so that camming tab 125 no longer closes contact switch 123, solenoid valve 127 will close. Accumulator 132 will allow for normal expansion or contraction of the hydraulic fluid, plus account for any volume increase due to movement of the crosshead rod 35 from upper chamber 128. Likewise, if secondary lever 26 moves downward so that camming tab 126 closes contact switch 124, solenoid valve 133 will be open thereby allowing fluid flow from lower chamber 130 to upper chamber 128 through conduit 134. The flow of fluid from the lower chamber 130 to the upper chamber 128 will cause the piston 131 to move downward thereby shortening the distance between pin 37 and cross pin 77 of intersecting crosshead 34. Again, the normal expansion of fluid may be accomodated by accumulator 132, as well as the decrease in volume caused by the movement of crosshead rod 35 from the upper chamber 128. Movement of the piston 131 will allow the secondary arm 26 to move upward until camming tab 126 releases contact switch 124 to deenergize solenoid 133. Therefore, by use of the float 115 and the servocontrol motor 118 as just described, the distance between pin 37 on secondary arm 26 and cross pin 77 on lever arm 25 may be varied in response to the tide.

Muletas axilares - amarilla (PAR) - Medicaltex 10, a better understanding of the crosshead 34 and its regulation depending upon wave height can be better understood. 1, every other float 24 is staggered with respect to the adjacent floats so that maximum effectiveness of the waves against the floats can be obtained. The limiting of the size of the wave or tide action also limits the force that can be exerted on the actuation device.

BACKGROUND OF THE INVENTION The present invention relates to a hydroelectric plant and, more particularly, to a wave actuated hydroelectric plant having a plurality of constant displacement pistons that are responsive to floats pivotally attached to a stationary structure wherein each individual piston will displace the same volume during each stroke.

1 is a perspective view of a hydroelectric plant embodying the present invention. 2 of the drawings, there is shown a cross-sectional view of the hydroelectric plant 20 and the first turbine section 21. The lever arm 25 has a float 24 connected through a vertical shaft 29 to a float control 30 located on horizontal lever 31. The horizontal lever 31 connects to lever arm 25 through pivot pin 32 with the horizontal lever 31 being periodically adjusted in response to tidal action to maintain vertical shaft 29 in approximately the vertical position as will be subsequently described.

It is yet another object of the present invention to provide a constant displacement piston operated by floats at the surface of the ocean with the stroke length of the piston remaining constant despite the wave height and tidal action. Ser. Dolor exterior de la rodilla . No. 684,796 filed on May 10, 1976 and having the same inventor as the present application. SUMMARY OF THE INVENTION It is an object of the present invention to provide a hydroelectric plant operating from wave action to generate power. While the preferred embodiment shows the hydroelectric plant as operating a turbine due to water flow therethrough, the wave action may also operate a piston that would pressurize a gas, such as the atmosphere. Operation of piston 170 will pressurize a gas, such as the atmosphere, which is then stored in an accumulation tank 171. The pressurized gas stored in accumulation tank 171 is then used to turn turbine 172 for operating a generator in a manner similar to the turbine 71 turning the generator 74. All of the equipment as shown in the alternative embodiment of FIG.
