FIRE-EXTINGUISHING AEROSOL GENERATOR Russian patent published in 2011 - IPC A62C13/22 

FIELD: fire-fighting means.

SUBSTANCE: invention refers to fire extinguishing, namely to systems working on the principle of using suspended fine solid particles of an aerosol generated by combustion stick of a pyrotechnic composition as fire retardants. The generator comprises a pyrotechnic stick equipped with a flame igniter electrically connected with an external starting arrangement and fastened by a layer made of a curing material with a body overlapped with a diaphragm; the body through an annular gap forms a reverse pathway to an outlet annular nozzle and is coaxially fixed in a thermally shielded case provided with a central projection and an axially clamped plate-type cover. The case is filled with liquid oil covering the body wherein the pyrotechnic stick supplied with the flame igniter is arranged; a combustible diaphragm adjoins the body diagram; and over the body, distributed transverse disks alternating with in-built bulkheads is axially clamped; the central projection of the case has radial holes and adjoins a bottom of the cover.

EFFECT: invention provides enhanced functional reliability of the generator.
