Patent ID: 7699150

Claim:
A hydrodynamic clutch device comprising: a housing which can be brought into working connection with a drive; a hydrodynamic circuit formed by a pump wheel and a turbine wheel in said housing; a bridging clutch comprising a friction area in said housing; a torsional vibration damper comprising a drive side transmission element, a takeoff side transmission element, and at least one energy storage group between said transmission elements; a first flow route for a fluid medium extending from a first flow passage to said friction area; a second flow route for said fluid medium extending from said hydrodynamic circuit to a second flow passage; and a sealing arrangement separating said first flow route from said second flow route, wherein the torsional vibration damper comprises a transmission element which can move relative to the drive side transmission element, the sealing arrangement being fixed to the transmission element which can move relative to the drive side transmission element and cooperating with the drive side transmission element to separate the first flow route from the second flow route, and wherein the sealing arrangement comprises a radially outer area which is separated from the drive side transmission element by a sealing gap.
