WebBasic operation of a gas spring. As the rod is pushed into the tube, the gas contained in the spring is compressed, increasing the pressure, with the compression of the gas creating the spring-like behavior. The piston attached to the rod allows the flow of gas across the piston and provides the means of controlling the flow of gas as the rod ...
