Abstract
A power sensing regenerator includes a pair of displacers (24 and 26) connected in tandem for dividing a flow of fluid from a pump (12) into predetermined proportions for servicing one or more loads (42). Flow control valves (32 and 34) regulate respective flows from the displacers (24 and 26) to the one or more loads (42). A control system, which includes differential pressure regulators of the flow control valves (32 and 34), responds to a difference between discharge pressures of the displacers (24 and 26) for reducing discharge pressure of the pump (12).
