Process for actuating a hydraulic prime mover through conversion of energy in water current

摘要

Process for actuating a hydraulic prime mover through conversion of energy in water current wherein the arrangement for carrying out the process comprises at least one set of three coaxially disposed pipes. The central or main pipe serves as a cylinder to receive the impulses of the water current while the two sleeve pipes serve for bypassing the main pipe. A complex piston consisting of a chamber containing an elastic working substance and provided with a conventional piston therein is slidable in the cylinder and connected to an engine crankshaft. Valve and lock means are provided to regulate movement of the complex piston so that the kinetic energy can first be absorbed and stored as potential energy and later released to actuate the engine.
