A hydrodynamic clutch device includes a clutch housing connected to a drive, a pump wheel connected to the clutch housing, and a turbine wheel connected to a takeoff, the turbine wheel and the pump wheel forming a hydrodynamic circuit. A bridging clutch which is essentially surrounded by the hydrodynamic circuit includes a piston and a friction surface which can be acted on by the piston to connect the drive to the takeoff independently of the hydrodynamic circuit, the piston having one surface facing a pressure space and an opposite surface facing the hydrodynamic circuit. A pressure circuit includes a first pressure medium line to supply the hydrodynamic circuit with clutch fluid and a second pressure medium line to supply the pressure space with clutch fluid. A seal at least reduces the exchange of fluid between the hydrodynamic circuit and the pressure space, and a throttle allows a defined exchange of fluid between the hydrodynamic circuit and the pressure space.
