Abstract: A fluid clutch includes a first transmission element and a second transmission element which is rotatable about an axis of rotation with respect to the first transmission element. Torque transmission surfaces of the first and the second transmission elements are located opposite one another in a working fluid region in which torque transmission coupling can be made selectively between the first and the second transmission elements by means of fluid. A valve arrangement can be actuated for selectively making and breaking a fluid flow connection between a fluid storage region and the working fluid region, in order respectively to allow and prevent the ingress of fluid from the fluid storage region into the working fluid region and a braking apparatus can generate a braking force acting on the second transmission element. Two components are movable with respect to one another within a limited range of movement by the transmission of braking force to the second transmission element.
