PROPELLANT FIRE-EXTINGUISHING DEVICE Russian patent published in 2016 - IPC A62C19/00 

FIELD: fire safety.

SUBSTANCE: invention relates to manual portable devices for rapid fire extinguishing. Propellant fire-extinguishing device includes two pyrotechnic charges arranged through thermal protection layer in case containers of plate form connected with gap between their flanges, thus forming output disk nozzle. In slot-type combustion chamber there is safety gasket. Initiation assembly is mounted in case. Case is fixed in bracket with handle, which posts are installed on flange portions attachment bolts. Case of initiation assembly is screwed into threaded hole of bracket up to stop in pyrotechnic charges, thus being adjoined to safety gasket, through symmetrical slots in case containers flanges and channel in resistant protective interlayer. Thermo protective layer is made from magnesite, filled with expanded material, mainly, vermiculite or pyrite, wherein bracket posts are fixed on diameter of containers so that bend of handle is placed in plane of centre of mass of device, and igniter initiation assembly is made in form of spring-loaded pin, coaxial to detonating cap.

EFFECT: proposed technical solution simplified prompt device start-up into operation, guaranteed providing specified fire-fighting efficiency.
