摘要：A hydraulic control arrangement is disclosed with an input pressure
compensator consisting of a proportional directional valve (1), one control side (Y) ofwhich is loaded with a throttled consumer load pressure and a prestressing spring andthe other control side (X) of which is loaded with a throttled pump pressure, and ahydraulically controlled control valve (ZV1) for the optional throttled connection of thetwo control sides of the proportional directional valve (1). Furthermore, an additionalpreferably electromagnetically actuated control valve is provided which optionally opensa bypass line to the hydraulically actuated control valve, in order to positively connect athrottled bypass connection between the two control sides of the proportionaldirectional valve.
