Abstract
A hydraulically controlled release system for a friction clutch particularly for a motor vehicle including an annular cylinder supported at a transmission housing and having an annular piston operatively engaged therein, the piston being connected with a diaphragm spring control member of the clutch. The end of the piston facing the clutch extends axially into the annular cylinder and the opposite end of the piston which faces the transmission rests against a radially outwardly bent edge of a bearing flange operatively mounted radially within the annular piston and cylinder. The bearing flange is guided with its outer side on the inner side of the annular cylinder and carries a release bearing which is operatively interposed between the diaphragm control spring of the clutch and the release bearing.
