ABSTRACT:
A hydraulic damper of the type having a cylinder defining an actuating chamber receiving hydraulic oil therein, a piston working in the actuating chamber, a piston rod with one end thereof secured to the piston and the other end thereof projecting from one end of the cylinder, a resisting force generating device mounted on the piston for controlling oil flow across the piston when the piston reciprocates in the actuating chamber, and a volume compensating chamber disposed adjacent to the actuating chamber and receiving gas and hydraulic oil therein. The hydraulic oil is caused to flow between the actuating chamber and the volume compensating chamber through a small hole. The cross-sectional area of the small hole is such that a pressure sufficient to actuate the resisting force generating device is generated in the actuating chamber with or without the aid of gas pressure in the volume compensating chamber when the piston moves in a contraction stroke, whereby the gas pressure in the damper is reduced substantially.
