Abstract (en)

[origin: WO9311363A1] A device for recovering energy, in particular potential energy in working machines, has a hydraulically actuatable working cylinder (3) linked to a hydropneumatic storage (4). At least another working cylinder (5) is provided, the working cylinders (3, 5) are mutually linked by their rods so as to transfer fluid and are linked to a hydraulic circuit having at least one pump, and the other working cylinder (5) is also linked at its piston side to a hydraulic circuit having a pump, so that the energy generated by the movements of the working machine can be profitably stored in a failure-proof manner and called back again at defined moments in time.
