The invention relates to a hydraulic clutch actuation system for controlling in particular a clutch-controlled compensation unit of a drive train of a motor vehicle, wherein a hydraulic pump is used for generating hydraulic pressure in a hydraulic fluid for the purpose of clutch actuation via a hydraulic clutch actuation device. Said hydraulic clutch actuation system is characterized in that the friction elements of a friction clutch to be oiled with clutch oil (cooling or lubricating oil) are supplied with the hydraulic fluid as the clutch oil. In this manner, the clutch can be oiled better and more reliably even at low vehicle speeds and high clutch load while ensuring a speedy dry running of the clutches and little power loss caused by clutch oiling.
