Abstract: A system is for braking a hydraulic working cylinder which is configured to be driven, for a motion, by an inflow pressure at an inflow end of the hydraulic working cylinder and an outflow pressure at an outflow end of the hydraulic working cylinder. The hydraulic working cylinder has no pump reversal. The system includes logic valves, and electro-proportionally actuatable control valves. The system is configured to control, by an electro-proportional adjustment of at least one of the logic valves, an outflow volume flow of the hydraulic working cylinder such that the outflow pressure is decoupled from the motion of the hydraulic working cylinder and coupled to the inflow pressure so as to lower the inflow pressure for the motion of the hydraulic working cylinder.

Abstract: A system for braking a displacement-controlled drive system (10), which can be driven by means of an inflow pressure and an outflow pressure at an inflow end and an outflow end thereof, respectively, for a motion, characterized in that by means of an electro-proportional adjustment of at least one valve element (26, 28, 126, 128) an outflow volume flow of the drive system (10) is controlled such that the outflow pressure is decoupled from the motion of the drive system and can be freely preset and coupled to the inflow pressure, which can in that way be lowered to the extent necessary for the motion of the drive system (10).
