Abstract
A high pressure gas cartridge having a sealing plate and a gas pressure regulator under the sealing plate in the passage for the gas. The cartridge is charged through a clearance space provided between the sealing plate or the gas regulator and the cartridge wall. The regulator operates when the inner pressure rises excessively and prevents the cartridge from rupturing or moving by permitting the gas to gradually eject through an orifice therein. The regulator controls the gas flow so that it is sufficient for a device employing the gas, but not sufficient to cause the cartridge to move or fly by reaction when the sealing plate is broken and permits the gas to freely flow out.
