ABSTRACT:
A hydraulic power system for operating a rotary-hydraulic motor includes a pair of hydraulic piston/cylinder assemblies each disposed in vertical disposition below a common water source and having cylinder heads interconnected by hydraulic delivery and supply conduits in a closed circuit including the motor which is operated by forward and reverse flow of liquid through the circuit effected by alternative rising and lowering of the respective pistons. The upper ends of the respective pistons are provided with water tanks which are filled from the water source and emptied into respective discharge tanks sequentially to provide the raising and lowering movements of the pistons. The system further includes various valve devices in the closed hydraulic circuit and in association with the water source and piston and discharge tanks for controlling the respective liquid flows in a manner providing the cyclical alternative reciprocation of the respective pistons.
