Abstract
An operation device for a friction clutch arranged in the drive train of a motor vehicle. The operation device includes a positioning servo arrangement with a pneumatic power cylinder arrangement. The pneumatic power cylinder arrangement acts on a clutch release sleeve arrangement. The positioning servo arrangement can be operated with a control valve that is connected to a pneumatic source depending on a command variable representing a desired position and an actual variable representing the axial position of the clutch release sleeve arrangement. The pneumatic power cylinder arrangement is arranged inside of the bell-shaped housing and the control valve is arranged outside of the bell-shaped housing or the bell-shaped housing is arranged at least partially inside of the bell-shaped housing, but is accessible from the outside and/or can be removed when the bell-shaped housing is attached to the combustion engine.
