Abstract
A regenerative hydraulic pump that allows for efficient operation of a hydraulic system under high pressure/low flow conditions that comprises a crankshaft providing a rotating inertial mass, and a regenerative hydraulic pump cylinder that comprises a pump cylinder housing, a pump piston mechanically connected to the crankshaft; and a compliant pressure chamber that stores a portion of the energy extracted by the pump piston during a pumping stroke for release back to the pump piston and to the crankshaft during a regenerative back stroke.
