Abstract:
1. A hydraulic control arrangement for the control of a consumer, comprising at least one mechanically operated continuously adjustable distribution valve with a subsequent pressure compensator down the line to which a load pressure of the corresponding consumer is applied in an opening direction and a highest load pressure of all controlled consumers is applied in the closing direction to a rear control chamber, wherein said highest load pressure is carried via an LS line to a pump regulator of a pump, wherein upon operation of a safety valve, the pressure compensator is brought into a closing position for closing the connection to the consumer, wherein a pressure compensator piston is moved toward its closed position by a spring, the LS line is connected to the reservoir by means of a flow control valve, the safety valve is arranged in the LS line between the pump regulator and the pressure compensator; and a pressure is tapped off by a first throttle from a pressure medium flow portion downstream of the pump and upstream of an outlet of the pressure compensator, and directed to the rear control chamber, upon a change-over of an interrupter valve.
