A regulating device (10) is connected to a hydraulic pump and tank, which has a first load port (16), from which a first hydraulic fluid feed line (18) emerges to the cylinder load-bearing pressure side (6) and a second load port (20) from which a second hydraulic fluid feed line (21) emerges to the cylinder opposing pressure side. The direction and extent of the hydraulic flow at the respective ports is controlled by the regulating appts. (10). - A pilot pressure-controlled load-holding check valve (23) is provided in a return connection (30, 26, 42, 31, 18) between the hydraulic cylinder load-bearing pressure side (6) and the regulating appts. |
