DISENGAGING DEVICE

The invention relates to a device for disengaging a clutch, in particular a clutch in the drive train of a motor vehicle, comprising a housing that is arranged concentrically about an axis and forms a pressure chamber in which an axially movable annular piston is arranged and a disengagement bearing that is designed for abutment on a disc spring of the clutch and is fastened to the annular piston, the housing being supported via a cover bearing on a cover of the clutch, wherein the cover bearing has a stationary inner ring, a rotating outer ring, and rolling elements arranged therebetween. The invention is characterised in that the disengagement bearing is arranged substantially within the inner ring of the cover bearing at least during part of an actuating stroke of the annular piston.
