Compressed gas spring functions as the support and buffer. It consists of pressure pipe, piston rod, piston, sealed guide sleeve, filler (usually inert gases or fuel-air mixture) and other components and connectors.Working principle: Fill inert gases or fuel-air mixture in the sealed cylinder to form high pressure which provides spring force for the piston rod's free bend and stretch by the charged gas acting on the difference in areas between the top and the bottom of the piston.
