Beschreibung
Zusammenfassung:	Hydrodynamic retarder device (4) comprising: at least one stator (7), in order to, jointly with at least one rotor (8), form a workspace (6) for a working medium and a clutch device for connection and disconnection to/from a power-train (3). The pressure in the workspace (6) is reduced to or below the vapour pressure for the working medium, in order to vacate the workspace of liquid working medium in connection with a disconnection from the power-train. The workspace is kept in an evacuated state until the reconnection of the retarder device (4) with the power-train (3) for subsequent braking operation. The invention also relates to a method and a vehicle.
