It comprises essentially a body (1), a pump retarder (2), a trigger finger (3), a spring (4), a top ring (5), a locking member (8) mounted at the end of a rod (6) integral with a securing ring (7), a spring (9), a locking finger (11), a spring (13), hinged paddles (14 and 15), a locking lever (16) and a spring (18). Upon a violent collision, the locking member (8) is drawn aside and releases the trigger finger (3) of which the retraction allows the rod (2a) of the retarder (2) to actuate the locking member (16) which, by releasing the hinged paddles (14 and 15), allows the retraction of the locking finger (11). |
