ABSTRACT:
A heavy duty hydraulic shock absorber having an inner tube in which is slidably mounted an impact receiving piston assembly. Upon application of an impact force on the piston assembly, the piston assembly is moved inwardly of the inner tube and fluid from the inner tube is metered through a plurality of exponentially disposed metering orifices into an accumulator chamber formed between the inner tube and an outer tube which encloses the inner tube. An adjustable, slidable metering spool is operatively mounted in the accumulator chamber, over the metering orifices, for regulating the flow of fluid through the metering orifices into the accumulator chamber.
