摘要：
A shock absorber is provided a piston stroke speed dependent linear variation characteristics of damping force. The shock absorber includes variable orifices in tandem fashion for achieving linear variation characteristics of damping force according to variation of the piston stroke. One of the variable orifices is provided with variation characteristics of flow restriction for a greater variation rate of the damping force in a low piston stroke speed range, and the other is provided variation characteristics of flow restriction for a greater variation rate of the damping force in the intermediate and high piston stroke speed range. The variable orifice may be provided in a piston assembly or in the alternative in a bottom fitting in the case of a double-action type shock absorber.
