Abstract: A bidirectional self-contained end-of stroke snubbing device (20) includes a housing (21), a rod (22) movable relative to the housing, a single fluid-filled variable-volume chamber (23) communicating with a fluid sump (24) through an orifice (65), and a lost-motion mechanism for selectively reducing the volume of the chamber proximate either end of the stroke of the rod-like member. The mechanism will force fluid from the chamber through the orifice to decelerate and cushion movement of the rod-like member relative to the housing proximate either end of its stroke.
