ABSTRACT:
A variable damping force shock absorber has a hollow cylinder, in which is disposed a thrusting piston for defining upper and lower fluid chambers. A fluid path is defined through the piston and a piston rod for establishing fluid communication between the upper and lower fluid chambers. A first flow restrictive orifice is provided in the fluid path which first flow restrictive orifice has variable flow restriction characteristics according to a first variation characteristic in relation to a piston stroke speed. A second flow restrictive orifice is also provided in the fluid path. The second flow restrictive orifice has a variable multitude flow restriction according to a second variation characteristic in relation to the piston stroke speed, which second variation characteristic is so determined as to establish, linear variation of damping force in relation to the piston stroke speed. A communication path is formed for establishing communication between the first and second flow restrictive orifices. The communication path has a first section extending radially and a second section extending axially and is defined between the piston rod and the piston.
