AUTONOMOUS FIRE EXTINGUISHING DEVICE Russian patent published in 2017 - IPC A62C13/00 

FIELD: fire safety.

SUBSTANCE: invention relates to devices for automatic fire extinguishing by means of fire-fighting gas-flame-shaped fire-control gauges generated in the combustion of pyrotechnic composition, which are sent in an organized manner to the protected volume; the devices are intended for use on vehicles, warehouses and industrial premises. The stand-alone extinguishing device includes a source of flame retardants, a means of initiating it in the form of a pulse starter comprising a spring-loaded stem seized by means of an open ring made of material with a thermomechanical shape memory installed in the head groove. At the end of the rod a nock stinger is fixed, which interacts with the primer placed in the mounting nozzle sleeve, communicating with the channel pyrotechnic checker, generating a functional aerosol during combustion, closed from the opposite end with a diaphragm with distributed outlets covered by the combustion membrane. On the nozzle sleeve coaxially tubular body, carrying a pulse starter, and the shell of the generator of a functional aerosol are mounted.

EFFECT: device is characterised by high functional reliability due to the creation of a membrane that closes the outlets of the diaphragm.
