ABSTRACT:
A clutch system includes a clutch device for positioning in a drive train between a drive unit and a transmission, and an actuating unit for hydraulically actuating the clutch device by means of at least one hydraulic slave-cylinder. The actuating unit has a hydraulic-medium delivery device for delivering a pressurized hydraulic medium, and a valve assembly, whose mediation allows the hydraulic medium to be supplied to and discharged from the slave-cylinder. The valve assembly comprises at least one supply valve, located in a hydraulic connection, between the hydraulic-medium delivery device and the slave-cylinder and at least one discharge valve, which is separate from the supply valve and located in a hydraulic connection, between the slave-cylinder and a hydraulic-medium reservoir.
