Abstract: A self-cleaning mechanism for a pneumatic central clutch release includes: a release piston which is coaxially arranged around a hollow shaft and is mounted such that it moves in the direction of an axis of the hollow shaft; and a housing which at least partially surrounds the release piston so as to form a pressure chamber between the hollow shaft, the housing and the release piston, which is sealed from the environment and can be connected to a fluid pressure source; and a cleaning chamber fluidically arranged between the pressure chamber and the environment. The cleaning chamber is able to be connected to the environment by way of a ventilation channel.

Abstract: A compressed-air control device includes at least one first component, and a second component arranged so as to be movable relative to the first component. A molded seal is arranged in a groove of the first component, and is in contact with the second component. A first chamber formed on one side of the molded seal between the first and the second components can be charged with a first pressure, and a second chamber formed on the opposite side of the molded seal between the first and the second components can be charged with a second pressure. The molded seal together with the first component forms at least one overflow valve.

Abstract: A pull-type racing clutch has an integrated clutch release device. A piston which can be actuated hydraulically is formed directly by an outer ring of a rolling bearing arrangement.

Abstract: The invention concerns a device for actuating a diaphragm spring clutch (20) for vehicles by means of a pneumatic, hydraulic or electric actuator (24), comprising a controller connected upstream of the actuator (24), whose output control variable actuates the actuator (24). To compensate for the strong nonlinearity of the releasing force over the releasing stroke that is typical of diaphragm springs, a controller is used, whose characteristic curve is plotted in such a way that this nonlinear curve of the releasing force is at least approximately compensated via a correspondingly coordinated actuation of the actuator (24), so that it remains essentially identical over the releasing stroke.
