How Gas Springs or Gas Struts are pressurized with nitrogen gas and then sealed?
Prior to testing and probably painting, the last stage of manufacturing a gas spring or gas strut is [B]pressurizing with Nitrogen[/B]. I was wondering how this step is done. I think it is filled with gas f[B]rom the rod side[/B] and the rod seal works as an [B]one way path[/B], meaning, nitrogen gas is injected into the cylinder with certain amount of pressure, and then when the injection is stopped, the pressurized nitrogen in the cylinder [B]pushes the seal back[/B] and seals the gas strut, but I’m not sure.
