ABSTRACT:
A hydraulic engine having a fluid pump for pumping a fluid medium under pressure to a fluid motor connected to the pump for being actuated by the fluid medium under pressure received from the pump. A control system regulates operation of the pump and motor so as to permit appropriate variation of speed of an output shaft of the motor. The fluid motor is a reciprocating motor, the piston of which is connected directly to a mechanism for translating the reciprocating motion into rotary motion, while the reciprocating movement of the pistons simultaneously actuates valves for sequentially directing the fluid medium under pressure to opposite ends of the piston in order to obtain a double-acting piston and cylinder operation.
