摘要： A ring-shaped sealing element (16) for sealingly closing a ring-shaped gap between the inner surface of a cylindrical wall and a concentric cylindrical piston which slides therein in the axial direction has two separate ring-shaped, axially adjacent parts (42, 44), of which the first part (42) is made of an elastomer material and the second part (44) of a stiff material. In order to ensure a as constant as possible opening and closing behaviour of a valve in co-operation with a sliding valve body, the two parts (42, 44) are releasably linked to each other and the part (44) made of stiff material forms a single piece with a ring-shaped, continuous axial projection (46) which extends almost completely through the part (42) made of elastomer material and has a face completely covered by the part (42) made of elastomer material. The ring-shaped, continuous axial projection (46) is designed and arranged in such a way that a radial wall thickness Si of part (42) made of elastomer material at its inner flank in the radial direction is approximately the same as a radial wall thickness Sa at its outer flank in the radial direction. The radial dimension S of the projection (46) equals maximum 70 % of the sum of the wall thicknesses Si + Sa.
