ABSTRACT:
An end-of-stroke bidirectional snubber for a suspension cylinder includes an elongate snubber element having a first flow regulating end portion co-acting with an annular edge for gradually restricting fluid flow from a head end chamber as the piston approaches an end wall of a casing to snub end-of-stroke retraction motion of a piston rod. The snubber element also has a second flow regulating end portion which coacts with a radial passage for gradually restricting fluid flow from a rod end chamber as the piston approaches an end of cap to snub end-of-stroke extension motion of the piston rod.
