ABSTRACT:
The present invention comprises an input drive system, which provides a plurality of phases of oscillating fluid flow, and an output drive system connected directly to the input drive system that is powered by the plurality of phases of oscillating fluid flow. The input drive system comprises a plurality of pistons that are caused to move in a reciprocating fashion by a power source. The power source may be a rotating power source, such as that provided by an electric motor, a diesel or petrol engine, or a turbine system. The input drive system comprises a cam ring attached to a rotating power source, a plurality of cam rollers in contact with the cam ring; and a plurality of pistons attached to the cam rings. The output drive system comprises one or more pistons that are attached to move in a reciprocating fashion by the oscillating fluid flow provided by the input drive system. The output drive system comprises a cam ring attached to a load, a plurality of cam rollers in contact with the cam ring, and a plurality of pistons attached to the cam rings.
