Abstract

A clutch system includes a clutch arrangement between a drive unit and a transmission, a pump arrangement which supplies pressure medium to the clutch arrangement at a pressure and rate of flow, and an operating medium supply arrangement which supplies an operating medium to the clutch arrangement at a pressure which is less than the pressure of the pressure medium and a rate of flow which is greater than the rate of flow of the pressure medium. The operating medium supply arrangement includes a pressure receiving element which is movable in a housing and has at least one pressure receiving surface which is exposed to the pressure medium, and an interaction element which is coupled to move with the pressure receiving element and has at least one interaction surface which interacts with the operating medium to produce a flow of the operating medium.
