Abstract
Hydraulic actuating drive for a clutch, including a control unit, a hydraulic pump which can be driven by a drive and which feeds a pressure accumulator, and an actuating cylinder which is connected via a control valve with the pressure accumulator. The drive of the hydraulic pump is provided with a sensor for detecting the power consumption by the drive, and signals are sent to the control unit so that the hydraulic pump is controllable depending on the power consumption of the drive.
