摘要

The plunger has transverse coupling slider (9) that is provided for selectively coupling the inner element (6) to housing (2). The housing is moved towards the eccentric cam by a biasing spring (10). The upper end (18) of biasing spring is indirectly acted upon the outer surface (4) or lower annular end (17) of the shirt-like element (5). A limiting element (20) is axially arranged between the inner shell (13) of shirt-like element and the outer shell (12) of the inner element.
