Abstract
The fire-extinguishing device contains the reservoir with the fire-extinguisher powder, the ejector, the pipes for supplying the compressed gas to the reservoir and the ejector, and the outlet pipe union. To improve the efficacy of fire-extinguishing due to the homogenous ejection of the fire-extinguisher powder, the reservoir is equipped with the elastic membrane. The ejector is designed with the slot. The cavity under the elastic membrane is open to the inlet nozzle.
