FIRE EXTINGUISHING AEROSOL GENERATOR Russian patent published in 2016 - IPC A62C13/00 

FIELD: fire safety.

SUBSTANCE: invention relates to stationary devices for extensional fire fighting. Fire extinguishing aerosol generator comprises igniter arranged in the bottom sleeve and connected to the terminals of switching unit of external control electric signals, and pyrotechnic candle resting on the crossbar body, between which thermo protective layer made of hardened material is located. Annular reversible channel communicated with receiver is formed by the perforated shell of outer cylindrical casing installed with a possibility of angular positioning in the support bracket. In the bottom part of thermo protective layer of the casing there is a distributing box, where the communication unit and igniter are installed. Bearing bushing has the shape of the longitudinal fire transmission tube, which is adjacent to the open end of the stick, coated with a flame-retardant screen, on which thermo protective layer is made of magnesite, including distributed in volume expanded filler made of heat-resistant material, primarily, vermiculite or pyrite.

EFFECT: suggested technical solution provides increased structural strength, performance and longer service life for fire extinguishing aerosol generator.
