Abstract
A wet clutch comprising at least one friction disk () which is loaded by a piston () against an end disk (). In order to run a forced pressure medium flow over the friction surfaces () of the wet clutch, two pressures cavities () having a connection in the region of the friction surfaces, are loaded with varying pressures. In order to improve such arrangements, the invention proposes that the leakage flow flowing over the supports of the friction disks is limited.
