Abstract: The disclosure relates to a hydraulic system having a hydraulically actuable working cylinder which has a cylinder housing with a piston-rod unit that is guided in longitudinal movement therein, is actuable in opposite directions and subdivides the cylinder housing into a piston chamber and a rod chamber, and having two proportional pressure control valves, of which one is assigned to the piston chamber and the other is assigned to the rod chamber, wherein a connecting line is connected in a fluid-conducting connection between the rod chamber and the proportional pressure control valve assigned to the rod chamber, said connecting line being guided to an input side of the proportional pressure control valve for the piston chamber such that, when the piston-rod unit is extended, the fluid displaced from the rod chamber passes into the piston chamber of the cylinder housing.
