Plunger, particularly for high-pressure fuel pump of internal combustion engine, has stage emanating from its outer web in sections, which is immanent at axial end for representation of turn out safety device to shell segment

摘要

The plunger (1) has a housing (2), which receives a roller (4) in the area of an end (3) for start-up of a periodic stroke generator and axially passes through beneath the roller from a bridge piece (6) connected to an inner casing (5). A stage (15) emanating from the its outer web in sections, is immanent at each axial end (14) for representation of a turn out safety device (11) to a shell segment (12). A stage portion (16) overlapping the axial end in a roof-like manner abuts at a complementary counter surface (17) of an upper side (9) of the bridge piece.
