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.
Claims10
An end-of-stroke snubbing device, comprising:
- a housing;
- a member movable relative to said housing;
- a single fluid-filled variable-volume chamber communicating with a fluid sump through an orifice;
- and
- a lost-motion mechanism for selectively causing a reduction of the volume of said chamber by motion of said member approaching either end of its stroke;
- whereby said mechanism will force fluid from said chamber through said orifice to decelerate movement of said member relative to said housing proximate either end of its stroke.
