A powder fire-extinguisher comprises reservoir with extinguishing powder contained under the pressure of the pressurized gas, the release element, the aligned uniaxial charging valve, the nozzle for the outlet of gas-powder mixture, and gas accumulator made as a tube. The gas accumulator is designed as extendible appliance with the openings at its bottom and the valves located at the acute angle in the direction towards the release element. The valves may be opened with the decrease of the pressure in the reservoir. |
