Abstract
A hydraulic energy recovery system (101) has an output drive unit (103), which can be actuated by a driver (102), and by which a hydraulic motor-pump unit (104) can be driven. In at least one energy feed position, the motor-pump unit supplies an energy storage device (106) and/or working hydraulics (107) with fluid. In a recuperation position, the motor-pump unit discharges fluid under pressure from the energy storage device (106) at least to the working hydraulics (107) and/or is used to actuate the output drive unit (103).
