Abstract
A clutch arrangement has a first pressure chamber for exerting load clutch piston and a second pressure chamber for accommodating clutch elements and for feeding fluid for cooling the clutch elements. A first clutch element is connected to a first clutch element carrier and a second clutch element is connected to a second clutch element carrier. The first clutch element carrier accommodates the clutch piston and the second clutch element carrier exerts load on a torsional vibration damper and radially encloses the clutch unit over part of its axial extent length. The clutch piston is equipped with a flow passage for flow connection between the two pressure chambers, and the first clutch element carrier has a flow passage which interacts with a flow-guiding element provided on the second clutch element carrier, that is oriented relative to the flow passage of the first clutch element carrier at an angle.
