摘要

The ring (3) has a connecting bar (4) and a U-shaped cross section that is arranged in a groove (1) of a piston (2). A flange (13) has a rectangular cross section, whose radial outer surface (13`) is relocated against a radial outer surface (2`) of a piston. An upper side of the ring and an upper side of an expander spring are arranged in an upper partial groove, and a lower side of the ring and a lower side of the spring are arranged in a lower partial groove.
