Abstract

Seal arrangement, comprising a piston (2) which is arranged in a hollow cylinder (1), passes with a transverse projection through a longitudinal split (3) in the hollow cylinder (1) and is sealed off by sealing rings (4) with a polymer sealing lip (4.1) from the hollow cylinder (1) and a sealing band (5) covering the longitudinal split (3), which sealing rings (4) are arranged at the ends of the piston. The sealing ring (4) is secured to the piston (2) in such a way that it cannot rotate and has a cross-section which is larger only in the area of the transition zone between the sealing band (5) and the hollow cylinder (1) than in the remaining peripheral areas and/or the sealing lip (4.1) is shorter in the axial direction and/or thicker only in the area of the transition zone than in the remaining peripheral areas. <IMAGE>
