An actuating device for a friction clutch arranged in the drive train of a motor vehicle. The actuating device has a positioning servo arrangement with a pressure-medium power cylinder arrangement which acts on a disengagement bearing arrangement. There is provision, for assigning to a pressure-medium subsystem, made up of the pressure-medium power cylinder arrangement and a control valve of the positioning servo arrangement, a pressure compensating orifice which, at least when the positioning servo arrangement is in a holding state, permits a defined pressure-medium pressure compensating flow, in order to influence at least one positioning behavior of the positioning servo arrangement.
