THROW-TYPE FIRE-EXTINGUISHING DEVICE Russian patent published in 2010 - IPC A62C19/00 A62C13/22 

FIELD: fire-fighting means.

SUBSTANCE: invention relates to fire-fighting equipment, in particular to devices generating gas-aerosol mixture of inhibitors of burning, and is intended for volumetric extinguishing of fire in closed premises by hand throwing of the device into fire centre. Device contains case consisting of two plate-shaped reservoirs, counter-fixed, with their flanges forming ring outlet nozzle for generated gas-aerosol mixture during burning of pyrotechnical charges, installed in each case reservoir through layer of construction gypsum, and unit of ignition, located under radial handle. Unit of ignition is installed in threaded bush of mounting clamp, fixed coaxially to through hole in reservoir, blocked with foam-plastic stopper and adjacent to fire-conducting inclined canal of communication with clearance between free butt ends of pyrotechnical charges, installed aflush with reservoir flanges. Both charges are autonomously packed in polymer film jackets, nozzle being formed by matching convexes, made on supporting surface of flanges and layers of construction gypsum being reinforced with metal mesh.

EFFECT: increase of action efficiency and reliability.
