ABSTRACT:
A variable damping valve of a shock absorber is capable of properly adjusting a damping force according to read conditions, travel conditions and the like while a vehicle is traveling, thereby improving ride comfort and control stability. A flow of oil is controlled to generate a damping force and the damping force is simultaneously adjusted according to pressure in a pilot chamber. The damping valve comprises an upper retainer communicating with a high-pressure side and a main valve installed below the upper retainer. The main valve comprises a valve body defining a pilot chamber, a disk ring installed on a top surface of the valve body, and a housing for containing the valve body and the disk ring and integrally confining the valve body and the disk ring by being curled at upper and lower ends of the housing.
