Abstract (en)
[origin: US6378570B1] A gas cartridge comprises a body 1 with a neck 2. A movable valve made as a ball 3 is disposed inside the body 1. A cap 4 is installed in the neck. The end of the cap 4 can be chamfered or expanded. The ball 3 can be manufactured from an elastic, resilient material, from an elastic, resilient material with a metallic powdered filler or be fully metallic in an elastic, resilient envelope. A method of charging the gas cartridge comprises placing a movable valve inside the body of the cartridge, turning the cartridge with its neck downward and charging the cartridge with a liquefied gas under a pressure, reducing the charging pressure with simultaneous closing of the neck by the movable valve, closing the neck with a cap, pressing-in the cap and welding the flange of the cap to the face of the neck of the cartridge.
