Abstract

A hydraulically operating clutch release includes a housing having a pressure chamber sealed by a roll membrane. A clutch bearing is axially displaceable in the housing. A support body abuts the roll membrane in the chamber, and resiliently engages the bottom surface of the pressure chamber in the axial direction, to prevent damage to the roll membrane.
