What is Gas Spring

Gas springs, sometimes called gas shocks/gas shock absorbers, gas pistons, or gas struts, are springs that pneumatically store energy. They are called gas springs because they receive operating pressure from highly pressurized (compressed) gas. They store this pressure as potential energy, and free it when the piston that seals the energy lifts.

In contrast, regular mechanical springs work using elastic deformation. Unlike coil springs that resist impacts due to their structure, gas springs resist shocks because they are powered with pneumatic energy in the form of a high-pressure gas in a cylinder.

Gas springs are similar to air cylinders, in that they both use a piston that compresses or extends based on the pressure in the chamber.
