(54) High pressure gas cartridge


(57) A high pressure gas cartridge with a double safety device, comprises a sealing plate (2) with a safety mechanism (21) and a gas regulator (3) which is provided at a nearer portion than the sealing plate (2) in the passage (11) forthe gas. Gas is charged in the body (1) speedily through a clearance (32) between the sealing plate (2) or the gas regulator (3) and the body (1). The safety mechanism (21) acts when the inner pressure rises excessively and checks the cartridge from rupturing or moving by letting the gas escape gradually. The gas regulator (3) regulates the gas flow to an amount which is enough for actuating a device or devices using the gas but which does not make the cartridge move or fly by reaction when the sealing plate (2) has broken and the gas becomes free for flowing out.
