FIRE-FIGHTING MODULE BY KOCHETOV Russian patent published in 2012 - IPC A62C35/00 

FIELD: fire safety.

SUBSTANCE: invention is designed to extinguish fires with automatic stationary or mobile plants. A fire-extinguishing module comprises a vessel, a balloon with a siphon tube connected to a sprayer and separated with a liquid level, filled with a fire-quenching fluid. At the outlet from a balloon there is a lock-start gear of pyrotechnical type. The siphon tube is made with continuous section and a diffuser at the end. The sprayer comprises a hollow cylindrical body connected to a nozzle, where there are jets arranged in mutually perpendicular planes. The vessel comprises a cylindrical part, a conical transition part and a cylindrical part with a larger size of a diametrical section. Coaxially to the vessel, in its lower part there is a nozzle. The cylindrical surface of the nozzle changes into a conical surface and closes with an end dead partition, with a jet in its centre arranged as axisymmetric to the nozzle and comprising cylindrical and conical throttling openings connected in series. The vessel and the nozzle form three coaxial internal cylindrical chambers. On the nozzle there is an additional row of jets, which are formed by mutually perpendicular vertical channels for passage of fluid and horizontal channels. The conical side surface of the nozzle is arranged with an angle at the top equal to 90°, and in an expansion chamber, perpendicular to its axis, there is a meshy sprayer installed.

EFFECT: higher effectiveness of fire-fighting due to increased efficiency.
