ABSTRACT:
This invention is a piston-cylinder hydraulic snubbing device to arrest or resist motion. The invention may be utilized as a snubbing device alone, or it may be incorporated into a hydraulically actuated piston-cylinder assembly. The principal feature is that an orifice, through which hydraulic fluid is forced, is in the form of a gap between the ends of a piston ring, which gap is varied by engagement of the ring with a tapered bore in the cylinder.
