Abstract (en)
[origin: WO2014032757A1] The invention relates to a hydraulic energy recovery system (101) having an output drive unit (103) which can be actuated by a drive unit (102) and by which a hydraulic motor-pump unit (104) can be driven which, in at least one energy feed position, supplies an energy storage device (1/6) and/or working hydraulics (107) with fluid; and which, in a recuperation position, 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).
