In a hydraulic clutch actuation system for controlling in particular a clutch-controlled compensation unit of a drivetrain of a motor vehicle, in which hydraulic clutch actuation system a hydraulic pump is used for generating hydraulic pressure in a hydraulic fluid for the purposes of clutch actuation by means of a hydraulic clutch actuation device, provision is made whereby the hydraulic fluid is supplied as clutch oil to the friction members of the friction clutch which are to be oiled with clutch oil (cooling and/or lubricating oil). In this way, improved and more reliable oiling of the clutch can be made possible even at low vehicle speeds and under heavy clutch load, wherein, despite this, very rapid dry-running of the cutches, and low power losses generated by the clutch oiling, are ensured.
