LOAD INDEPENDENT FLOW DISTRIBUTION CONTROL ARRANGEMENT WITH A VALVE ARRANGEMENT FOR LIMITING THE LOAD PRESSURE IN THE LOAD REPEATER LINE

摘要

A load independent flow distribution control arrangement for at least two hydraulic users is disclosed, with an adjuster pump, the setting of which is altered depending upon a user load pressure in a repeater line, each user being provided with a proportioning diaphragm with a serial pressure equaliser. Should a load pressure limit for a user be exceeded, the side of the completely pilot-open regulator piston in the pressure equaliser, acting in the closing direction and corresponding to said user, is fed the pressure of the next lowest load user, by means of the above valve arrangement.
