Abstract
A control device, for a hydraulic consumer () and susceptible to vibrations, includes a valve () having a control spool () controllable by an actuating device (). The valve () has a pressure supply port (P), to which a pressure compensator valve can be connected, which can be supplied with pressure fluid from a pressure supply device. The actuating device () has a motor (). A load-pressure-dependent force on the control spool () can be generated by a control device (). That force at the control spool () acts on an electronic motor controller () of the DC motor (), which detects a change of the force and acts as a damping of the vibrations of the consumer () against this change of force.
