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.
