A seal, in particular for a hydraulic piston-cylinder arrangement within a hydraulic path for clutch or brake actuation, comprises a first sealing element, wherein the first sealing element has a basic body and at least one first sealing lip and the first sealing lip extends from the basic body in the direction of a pressure chamber and has a first sealing contour, wherein the first sealing contour makes contact with a first surface of the piston-cylinder arrangement for the purpose of sealing, having a reinforcement, wherein the reinforcement bears against the basic body of the first sealing element, and wherein the reinforcement has at least one first projection. According to the invention, the first projection is arranged between the first sealing lip and the first surface and bears at least partially against the first sealing lip, and the first projection is formed along the first sealing lip up to the first sealing contour. In this way, a seal can be provided which ensures an adequate sealing action in the low-pressure range and in the high-pressure range and by means of which the generation of noise, in particular as a result of the so-called stick-slip effect, can be reduced. |
