ABSTRACT:
This invention is a reciprocating piston to piston device that can function 1) to increase or decrease pressure in a hydraulic or pneumatic system with minimal energy loss or 2) as a hydraulic or pneumatic pump or motor. The input and output fluids may be the same or different. The energy transferred or pumped depends on the size of the input piston, the pressure of the input fluid, and rate of reciprocation.
