ABSTRACT:
A linear motion damper is disclosed which comprises a hollow sleeve member, a rod reciprocating within the sleeve member, and a piston adapted to engage a fluid filled cylinder to provide resistance to linear motion by the exertion of lateral fluid pressure between the rod and the sleeve. The damper of the present invention exhibits greater efficiency and durability in operation, and is adaptable for a wide variety of applications.
