A hydrodynamic clutch device includes a pump wheel, a housing connecting the pump wheel to a drive, a turbine wheel connected to a takeoff, the turbine wheel being located in the housing and cooperating with the pump wheel to form a hydrodynamic circuit, and a bridging clutch located in the housing and having a piston located between the hydrodynamic circuit and a pressure space. The piston is movable between an engaged position and a released position. At least one through opening in the piston allows an exchange of clutch fluid between the hydrodynamic circuit and the pressure space regardless of the position of the piston and a non-return valve allows only flow from the hydrodynamic circuit to the pressure space when the clutch is released.
