GENERATOR OF EXTINGUISHING AEROSOL Russian patent published in 2013 - IPC A62C13/22 

FIELD: fire-prevention facilities.

SUBSTANCE: invention relates to the field of fire fighting, namely to devices that generate gas-aerosol fire retardants designed for extinguishing fires in closed or semi-enclosed volumes. The extinguishing aerosol generator comprises a cylindrical housing and body with a lid and bottom, a mixing chamber, and also an activator and the pyrotechnic charge. The housing and the body are coaxially mounted with each with an annular gap for induced air. The mixing chamber is formed by the side walls of the housing. The pyrotechnic charge is set inside the body with provision of the possibility of formation of an ejecting aerosol chamber. Inside the body there is a layer of material cooling the aerosol. The generator is made with the ability of aerosol release to the protected area. The cylindrical housing and the body are interconnected coaxially. The bumper is installed parallel to the bottom which is fixed providing partial overlapping of the lateral surface of the body and forming around the body of an annular nozzle for ejecting aerosol release. The layer of the aerosol cooler is placed in series with respect to the pyrotechnic charge to form additional free volume with the function of combustion chamber. The ejecting aerosol chamber is formed between the bottom of the body and the bumper. The bottom is made perforated.

EFFECT: optimal combination of performances of extinguishing efficiency, temperature of gas-aerosol spray and the intensity of supply of the extinguishing aerosol to protected area with a low degree of tightness.
