摘要

Part (1) has hydraulic play compensating element (2), which in its housing (3) is positioned in seat (4) on part and has place for gas change valve on side facing away from seat. Housing has hole (7) in which a pressure piston (8) with outer lining (10) is arranged. A thin-walled body (11) supports the pressure piston directly against the base (12) of seat. To fix the body a surrounding spring collar (13) or spring tongues jut out orthogonally, which lies radially tensioned to the outside, lies against the inner lining of the pressure piston.
