PURPOSE: The valve structure of a pressure sensitive shock absorber is provided to improve the ride quality of a vehicle by reducing low speed damping force regardless of middle-high speed damping force. CONSTITUTION: A piston valve(20) is formed on the outside of the piston rod(13) of a shock absorber. The inside of the cylinder(10) in the shock absorber is partitioned into two spaces. Damping force is generated by operating the cylinder in the shock absorber. A control valve is installed in the piston rod. When the piston rod moves at low speed, the control valve is in an opened state. When the piston rod moves at middle-high speed, the control valve is in a closed state.
