Date Aug. 16, 1984.A device in machines (1) which are driven by means of a hydraulic cylinder, such as hydraulic presses and the like, and which has at least one pump (5) for the hydraulic fluid which pump is driven by a driving machine (6) through an energy accumulator, for example a flywheel (7). The object of the invention is to provide a considerable energy saving and recovery of energy. This has been achieved by at least one driving unit (5) connectable to the hydraulic system in the machine, said driving unit being arranged to bring back the elastically stored energy in the machine to the energy accumulator (7) during the decompression phase of the machine. |
