FIRE EXTINGUISHING AEROSOL GENERATOR Russian patent published in 2017 - IPC A62C13/00 

FIELD: fire safety.

SUBSTANCE: generator is proposed comprising a housing provided with an aerosol forming agent cartridge and a cooling cylinder of a larger diameter. The cartridge is installed inside the housing with a guaranteed gap filled with a heat-insulating layer. The cooling cylinder partially covers the housing to form a ring ejection gap. The housing is closed by a lid with an igniter and circumferentially distributed through holes. The free volume of the housing between the cartirdge and the lid is a combustion chamber. The thermal insulation layer is made of heat-resistant elastic material. The channel connecting the inlet and outlet sections of each through-hole is tilted to the inner surface of the cooling cylinder. In the internal volume of the cooling cylinder, a swirler is rigidly fixed on the igniter housing.

EFFECT: generator allows to increase fire extinguishing efficiency due to a significant reduction of high-temperature and fire-dangerous zones by creating conditions for provision of a curvilinear shape of the fire extinguishing aerosol trajectory within the internal volume of the generator, while increasing the generator's strength parameters during storage and under more severe operating conditions.
