Abstract
In a fluid-friction clutch with a disc stack actuable by an adjusting piston and having resilient spacer parts, the viscous fluid escapes from the shearing gaps between adjacent discs of the stack into a compensating chamber located radially on the outside in relation to the disc stack, in order to ensure a completely torque-free lifting position of the clutch when the adjusting piston is not actuated.
