SUBSTANCE: device for powder fire-fighting uses a cylindrical casing with a bottom filled with fire- extinguishing powder, unit with a pyrotechnical charge and igniter located in the bottom and separated from powder by a piston, and a cover sealing the casing on the side of the open end face. The piston has perforated holes, whose centers are arranged symmetrically, uniformly on circumferences concentric relative to the piston axis. The total area of perforated holes makes up 3.5 to 25% of the piston area. The specific value of the total area of perforated holes is selected proceeding from the required distance of ejection of dispersed flow of fire-extinguishing powder. EFFECT: enhanced efficiency. 1 cl, 2 dwg
