Abstract
The fluid-pressure ram, for controlling a clutch release bearing for an automobile clutch, has two variable-volume control chambers which follow each other axially and comprise a primary chamber which is fed with pressurized fluid and which is axially delimited sealingly, to the front by a fixed base and to the rear by a movable wall integral with a shell, and a secondary chamber which is axially delimited sealingly, to the front by the movable wall and to the rear by the piston, the movements of the fluidtight movable wall bringing about a decantation of a fluid contained in an intermediate chamber to the secondary chamber, and vice versa, the said shell separating the intermediate chamber from the secondary chamber.
