Leakage joint with securing lock, for combustion engine fuel injection system

摘要

A leakage connection/joint for mounting a leakage line to a fuel injector (1) has a connection gland (61) formed integrally with the injector body (11), an connection nipple (62) which engages with an insert (91) in an aperture in the gland (61), and an axial locking device which retains the gland (61) in its end position on the insert (91). The locking device forms a locking joint (10) between the gland (61) and the nipple (62), more specifically the locking joint is a bayonet fastening with a restoring lock.
