A shock absorber having a housing with a piston chamber and a radially spaced accumulator chamber. A piston rod having a piston at its inner end is slideably mounted in the piston chamber, while the outer end of the piston rod extends outwardly from the shock absorber housing wherein it is provided with a striker plate which is initially positioned for engagement by a load to be decelerated. The fluid passage between the accumulator and the piston chambers is provided with a tapered metering slot designed to communicate a lesser amount of oil between the piston and the accumulator chambers as the piston is decelerated, resulting in a gradual deceleration of the load exerted on the piston. An adjustable metering valve carried by the shock absorber housing is utilized to communicate oil from the piston chamber when a load is exerted on the striker plate which is less than the maximum amount the shock absorber may receive. A spring is carried by the shock absorber to return the piston rod to its initial position after the shock load has been dissipated so as to normally maintain the piston rod in an initial position ready for the receipt of a load and to decelerate the same.
