ABSTRACT:
A method for filling gas into a cylindrical container having a rod slidably extending from one end thereof. The method comprises forming passage means in the rod at a position adjacent to the inner end thereof, projecting the rod outwardly to its maximum extending position so as to form a gas filling passage by said passage means across an annular seal member which normally engages the rod sealingly and slidably, filling high pressure gas into the container through the gas filling passage, and moving the rod inwardly relative to the seal member to close the gas filling passage.
