A gas spring, a method of filling a gas spring with pressurized gas and an installation for performing the method.

摘要

A gas spring (12) must be filled with pressurized gas through an opening. This opening must be closed after the filling operation while maintaining the gas pressure within the gas spring (12). According to an illustrative example of the invention, the filling opening (24) is bored by a laser beam, while the location of the opening to be bored is confined within a filling chamber (14). After such laser boring of the opening (24), pressurized gas is admitted to the filling chamber (14) and flows from the filling chamber (14) into the gas spring (12). Hereinafter, the opening (24) is closed again by directing the laser beam against an annular zone surrounding the opening (24).
