Beschreibung
Zusammenfassung:	This invention relates to an apparatus for recuperating hydraulic energy in a working machine, with at least one first differential cylinder piston device (100) with a differential cylinder (1) and separate rod (2) and bottom (3) sides, with at least one hydraulic accumulator (16) which is hydraulically connectable with the differential cylinder piston device (100), wherein the potential energy of the differential cylinder piston device (100) retracting under pressing load is at least partly storable in the hydraulic accumulator (16), and wherein the rod (2) and bottom (3) sides are connectable with each other via at least one brake valve (6) for recirculating hydraulic fluid from the bottom side (3) into the rod side (2).
