Insertion tool for fitting locking rings in annular groove in cylinder wall

摘要

The locking ring (30) has an inner groove (12) and first and second radial surfaces (46,48). The edge (62) of a support frame (60) has a stepped built into it to form a radially extending shoulder (66) and an axially protruding section (68). The shoulder is designed so that it interacts with the first radial surface of the locking ring, and the axially protruding section seats in the locking ring in the proximity of the inner circumference (42). A number of radially projecting fingers (95) extend through the axially protruding section.
