FIRE EXTINGUISHING AEROSOL GENERATOR Russian patent published in 2021 - IPC A62C13/22 

FIELD: fire-prevention equipment.

SUBSTANCE: invention relates to fire-fighting equipment, namely to fire-extinguishing aerosol generators (FAG). FAG is proposed, comprising housing, front part of which is equipped externally with coaxially installed shell, cover provided with igniter and circumferentially distributed through holes, aerosol-forming balloon, heat-insulating layer, combustion chamber, a swirler rigidly secured to the housing cover, a swirler in the form of a disk with trapezoidal plates made integral with it, a cooling cylinder equipped with a truncated cone diverging towards the front part of the housing, Lock ring is arranged at cooling cylinder outlet and ejector represents a set of annular gaps between housing and shell and between shell and truncated cone of cooling cylinder. Checker is arranged in metal shell, heat-insulating interlayer is located between cartridge and shell, shell is installed coaxially in housing with gap, elastic non-heat conducting gaskets are installed between side and bottom surfaces of shell and housing. Each swirler plate is made solid or has through hole. An elastic element pressing the open end of the block is attached to the bottom part of the igniter.

EFFECT: invention substantially reduces high-temperature and fire-hazardous zones by complex, air and mechanical temperature reduction, accordingly, fire-extinguishing aerosol at output from FAG and the hottest surfaces of the housing, with simultaneous reduction of physical losses of fire extinguishing aerosol.
