PURPOSE: A self leveling shock absorber is provided to ensure improved response speed because of a simplified flow path structure that minimizes pressure loss. CONSTITUTION: A self leveling shock absorber comprises a base shell(110), an inner tube(112), a piston rod(120), a piston valve(130), an outer tube(114), a body valve(140), and an opening/closing ring(151). The inner tube is installed inside the base shell and forms a low pressure chamber(111) in a gap formed between the inner tube and the base shell. The piston rod is installed inside the inner tube. The piston valve is coupled to the end part of the piston rod and divides the inside of the inner tube into an extension chamber(113) and a compression chamber(115). The outer tube is installed in the lower outer side of the inner tube and forms a high pressure chamber(118) and a gas chamber(119) which are divided by a diaphragm(117) in a gap between the outer tube and the base shell. The body valve is installed in the bottom of the inner tube and controls fluid flow between the high pressure chamber and the low pressure chamber. The opening/closing ring is formed in the lower part of the inner tube and selectively opens/closes a discharge hole for discharging working fluid in the compression chamber to the low pressure chamber by interlocking with the piston rod. |
