Abstract
Disclosed herein is a valve structure of a shock absorber which forms flow channels in two directions of working fluid passing through the valve structure so as to slow change of damping force when the moving velocity of a piston is changed between a low velocity and a middle and high velocity and forms one of the two flow channels as a variable flow channel to improve ride comfort of a vehicle. The valve structure includes a piston valve assembly installed at the end of the piston rod and operated to generate damping force varied according to moving velocity of a working fluid, and a variable valve assembly moving together with the piston valve assembly to vary damping force to slow change of a damping force curve when the flow velocity of the working fluid is changed between a low velocity and a middle and high velocity.
