Abstract

The clutch includes a sealing arrangement (112, 134) and at least one resetting element (170, 172) for an operating piston (110, 130) which returns the piston to its starting position when not activated. The resetting element is guided on its radial outer circumference along one of the sealing arrangements (112, 114, 134, 136). The resetting element can be formed as a plate spring assembly mounted radially inside an axially extending section of a sealing element holder.
