Abstract: A nonadjustable shock absorber that can accommodate for variations in weight, and propelling force, and to provide a specific deceleration or reaction force. The shock absorber provides dual function metering that combines soft contact dampening with the self compensating ability to decelerate a wide range of weights.

Abstract: A nonadjustable shock absorber that can accommodate for variations in weight, and propelling force, and to provide a specific deceleration or reaction force. The shock absorber provides dual function metering that combines soft contact dampening with the self compensating ability to decelerate a wide range of weights. The shock absorber includes a low pressure zone, a hydraulic cylinder having a high pressure zone chamber, a piston in said cylinder for movement under a shock load through a predetermined stroke length, a fluid pathway metering control means, having four fluid metering pathways of which the first three fluid metering pathways are approximately linear spaced apart, for controlling high pressure fluid escaping from the high pressure zone chamber into the lower pressure zone, ahead of the piston as the piston moves from an initial position in response to a shock load through a total stroke to a final position, to create five control zones during the compression of the shock absorber.
