Abstract
A sealing arrangement, particularly for a rail vehicle slack adjuster, between a generally tubular housing (7) and a rod (1), which is axially and rotatably movable relative thereto, has a cup (10) engaging the rod with a sealing ring (11) so as to be movable with the rod. This cup extends along the rod over the free end of the housing so as to form a type of labyrinth sealing. The cup is preferably provided with a protective and guiding internal ring (12) cooperating with the housing.
