ABSTRACT:
A hydraulic engine for transforming the energy of a flowing current of water into a pressure head of water. The engine is mounted on a platform supported by floats and fitted with a series of paddles linked by drive chains which pass about a pair of drive wheels such that flow of water over the platform causes the paddles to move in the direction of flow to rotate the drive wheels with the paddles and chain being elevated above the water level for return travel. A drive wheel is joined by a shaft to a cam wheel against which an end of a piston shaft is engaged so that rotation of the cam wheel causes reciprocal travel of the piston shaft with the piston enclosed in a cylinder that pumps water up through a vertical pipe to create a pressure head of water for driving a generator engine. The cam wheel is shaped so that the reciprocal travel of the piston may be varied depending upon the radial position of the piston shaft. A telescopic hydraulic unit supports the cylinder on the platform so that radial position of the piston shaft may be varied to suit the condition of water flow.
