Sealing system for piston-and-cylinder units comprises at least one fiber-free sealing element and a further sealing element constituted a ring set with a harder wear resistant glide ring and an outer softer sealing ring

摘要

At least one of the sealing elements (42, 44, 46, 48) is free from fiber material. A further sealing element (34) is constituted as a sealing ring set (36, 38) in which a harder wear resistant glide ring (38) is inserted into a softer sealing ring (36) provided with a narrow sealing lip (40) next to the glide ring.
