ABSTRACT:
In a hydraulically operable release arrangement for clutches, especially for vehicle clutches, the release force is transmitted to the plate spring or the like of the clutch by way of a piston, a fixed bearing ring, a multiplicity of rolling bodies, and a rotating bearing ring. The piston is movably arranged in a housing and is biased by a helical spring arranged in a pressure space formed between the piston and the housing. The piston and the housing are each provided with an axial projection. In order to secure the piston against rotation and to damp vibrations in the piston without additional machining or special parts, the helical spring is arranged with its spring ends abutting the axial projections such that rotation of the piston in the direction of rotation of the rotating bearing ring is prevented.
