<p>A device for recovering energy in working machines, with at least one power drive, which can be actuated to move a load mass back and forth, and with an energy storage system (16) which absorbs the energy released in the movement of the load mass in one direction and which makes it available for a subsequent movement in the other direction, is characterized in that there is an energy storage system in the form of an accumulator cylinder (16) which, mechanically coupled to the load mass, stores pneumatic pressure energy for movement in one direction, and, for movement in the other direction, acts as an auxiliary working cylinder which supports the power drive and which converts the stored pressure energy into driving force.</p> |
