Abstract
A resilient cage (100) is provided for retaining a check-valve (56) in registration with a passageway (54) through an end wall of the static plunger (48) for controlling fluid flow from a first fluid chamber (50) into a second fluid chamber (60). Static plunger (48) includes an annular groove (52) in its outer surface proximate the end wall and cage (100) includes a radially inwardly extending flange (6) that is adapted to extend into groove (52) and secure cage (100) in the manner of an end cap about the end of static plunger (48). Cage (100) also serves to retain static plunger (48) together with a dynamic plunger (28) containing chamber (60) against the force of a spring (64) tending to separate plungers (28 and 48) after assembly.
