Abstract
An axially movable switching sealing ring within a groove having an axial width greater than the axial width of the ring, in particular in the piston of a piston-cylinder unit, where the switching sealing ring has sealing surfaces on its upper side surface, lower side surface and radial outer wall surface in each instance. The upper and lower side surfaces each have an axially relieved section adjacent the radially outer diameter of the ring, so that the upper and lower sealing surfaces are formed optimally by only part of the upper and lower side surfaces.
