Workingprinciple: Fill inert gases or fuel-air mixture in the sealed cylinder to formhigh pressure which provides spring force for the piston rod's free bend andstretch by the charged gas acting on the difference in areas between the top andthe bottom of the piston.

Gas spring is evidently superior to ordinarymechanical springs in the following aspects:
1. It features relatively lowspeed and minor change of dynamic force (the elastic coefficient X is between1.2 and 1.4) for easy control.
2. Its linear spring facilitates a quitebuffered and comfortable motion.

Other Characteristics of GasSpring:
1. Gas spring mainly for support can only be located at whichcompression and extension are required. It cannot stop by itself during thestroke.
2. Gas spring is energy-saving, eco-friendly and easy to install withsecure use and low noise.
3. Gas spring provides excellent buffer all theway for a stable and smooth stroke.

It is widely applied in automobiles,aerospace, office furniture, construction machinery, etc.
