ABSTRACT:
A variable damping force shock absorber includes a cylinder defining therein first and second fluid chambers separated by a valve body. The valve body defines first and second fluid paths for fluid communication between the first and second fluid chambers. A harder damping characteristics valve is associated with the first fluid path. On the other hand, a softer damping characteristics valve is associated with the second fluid path. The valve body has a pair of coaxial arranged grooves. The inner groove is in communication with the first fluid path. Valve seats are formed along respective outer circumference of the inner and outer grooves. The second fluid path is provided with means for varying the fluid path area.
