Pneumatic Shock Absorber is a shock absorber developed since the 1960s. Its structural feature is that there is a floating piston in the lower portion of the cylinder, and high pressure nitrogen is filled with high pressure nitrogen in a closed air chamber formed at one end of the floating piston. The O-seal ring is equipped on the floating piston, which is completely separated from oil and gas. The working piston is equipped with a compression valve and an extension valve that vary the channel cross-sectional area thereof. When the wheel is jumped up and down, the working piston of the damper is done in the oil, causing an oil pressure difference between the upper and lower cavities of the working piston, and the pressure oil is pushed open and turned back and forth. Since the valve produces a larger damping force to the pressure oil, the vibration is attenuated.
Features of Pneumatic Shock Absorber:
(1) High pressure air is not sensitive to temperature;
(2) Suitable for sports and game driving.
(3) The road feel is clear and the control is good.
(4) Suitable for long-distance driving.
