Abstract

An operating device of a friction clutch arranged in the drive train of a motor vehicle, having a positioning servo arrangement with a pressure medium power cylinder arrangement located inside the housing bell and acting on a clutch release bearing arrangement. The invention that the pressure medium power cylinder arrangement, an input element arrangement associated with a control valve and, in some cases, additional anti-tilting moment devices are embodied and/or adjusted to each other and, in some cases, to the clutch so that the force resulting from the forces exercised by the pressure medium power cylinder arrangement, the input element arrangement and, in some cases, the additional anti-tilting moment devices directly or indirectly on the clutch release bearing arrangement or the clutch release bearing arrangement side of the pressure medium power cylinder arrangement, during at least one clutch operation phase, are at least substantially coaxial to the clutch axis.
