Abstract: A dampening shock absorber for retrofit or original construction with a conventional gas charged or hydraulic shock absorber having a tubular housing. There is provided a compression coil spring and spring retainer members disposed coaxially relative to the tubular housing. The tubular housing, the compression spring and the spring retainer members are longitudinally moveable relative to one another, and at least partially enclosed by a longitudinally movable outer protective sleeve. The sleeve is closed at one end and secured to the distal end of a piston rod extending outwardly of the shock absorber housing. Longitudinally spaced stops are provided on the tubular housing, and on the outer sleeve to limit the longitudinal movement of the operating and interacting components. Another embodiment of the invention provides an adjustment mechanism on the outer sleeve for adjusting the distance between the longitudinally spaced stops.

Abstract: Flow control valves (10) and (80) each include a cylindrical body (11) or (82) that is open through a number of ports (13), (14) and (15), the ports to be opened and closed by a resilient ball (16) that is selectively moved into and out of alignment with each port by lowering and turning a valve basket (15) and (60). The valve basket has co-planer essentially parallel arms that extend from ends of a web wherebetween the resilient ball is caged, which valve basket is secured to the end of a valve basket stem (19) or (89). The valve gasket is displaced vertically and turned by an actuator (48) or (94), through a handle (49) or (109), the turning of which handle operates through a system of opposing upper and lower cams (40) and (23) or a clutch cam system (81) to both vertically displace and turn the valve basket system stem and valve basket.

Abstract: A dampening shock absorber for retrofit or original construction with a conventional gas charged or hydraulic shock absorber or strut having an annular sleeve telescoped in sliding engagement over an inner sleeve to provide therewith a spring biasing to return the shock absorber to a null state after a displacing force has been removed therefrom.
