摘要：The invention relates to a hydraulic control arrangement, for control of a user(6, 8), with at least one mechanically-operated continuously-adjustable distribution valve(16), with a subsequent LUDV pressure compensator (24) down line. In order to lock theuser the controller is provided with a spring holding the pressure compensator piston ina closed position. Furthermore, the LS line carrying the highest load pressure of all theusers is connected to a tank by means of a flow regulator (12), whereby the pumpcontrol may also be relieved by the flow regulator (12) in the sense of a reduction in thepumped volume. According to the invention, the LUDV pressure compensator (24) maybe pressure equalised by means of a nozzle (98), whereby a connection between the LSline and a section of the pressure medium flow path downstream of the pump andupstream of an outlet (74) is generated. Said nozzle is preferably integrated in thepressure compensator piston.
