BUFFER DEVICE HAVING A SELF-ADJUSTING ABUTMENT

摘要

A buffer device with a self-adjustable stop comprises a buffer head (5) in the form of a shank presenting along its length a flat and touching ribs or grooves (6), and a socket (8) into which the buffer head in the form of a shank can be driven axially, serration by serration. The device further comprises an annular ring (7) inserted axially in an axial bore in said socket and presenting a bottom edge defining a thrust ramp. The ring has an inner surface presenting a smooth strip and an adjacent serrated strip such that actuating the ring by turning it causes the buffer head to be raised and its axial position to be blocked.
