Abstract

A clutch system includes a clutch device with at least one clutch arrangement for installation in a motor vehicle drive train between a drive unit and a transmission. The at least one clutch arrangement is actuated by a slave cylinder using a pressure medium which is supplied to the clutch device by a first pump. A further medium is also supplied to the clutch device by a second pump arrangement as an operating medium used during operation of the clutch device. The further medium is selectively supplied as a pressure medium to the slave cylinder.
