Abstract (en)
[origin: WO2011054408A1] A hydraulic control arrangement is disclosed with an input pressure compensator consisting of a proportional directional valve (1), one control side (Y) of which is loaded with a throttled consumer load pressure and a prestressing spring and the other control side (X) of which is loaded with a throttled pump pressure, and a hydraulically controlled control valve (ZV1) for the optional throttled connection of the two control sides of the proportional directional valve (1). Furthermore, an additional preferably electromagnetically actuated control valve is provided which optionally opens a bypass line to the hydraulically actuated control valve, in order to positively connect a throttled bypass connection between the two control sides of the proportional directional valve.
