The seal is formed by a sealing ring (13) which has a seal housing (14) of annular shape, which has an essentially U-shaped cross-section, in which an inner ring (19) and an outer ring (20) are arranged. The inner ring (19) is elastically resilient, while the outer ring (20) is used as a sealing element. The invention furthermore relates to a valve fitted with such a seal, a hollow piston (9) which can preferably be used in this case, and a method for its manufacture. <IMAGE></p> |
