Abstract

A hydrodynamic clutch includes a housing which can be brought into working connection with a drive; a hydrodynamic circuit formed by a pump wheel and a turbine wheel; a torsional vibration damper having a drive side transmission element, a takeoff side transmission element, and at least one energy storage group between the transmission elements; and a bridging clutch including first friction elements connected to the housing and second friction elements connected to the drive side transmission element. A first flow route extends from a first flow passage to the friction elements, and a second flow route extends from the hydrodynamic circuit to a second flow passage. A sealing arrangement cooperates with the drive side transmission element to separate the first flow route from the second flow route.
