VOLUME AEROSOL FIRE EXTINGUISHING APPARATUS Russian patent published in 2003 - IPC

FIELD: fire-fighting equipment. SUBSTANCE: apparatus has cooling cylinder and casing, which are coaxially arranged in spaced relation with respect to one another for defining injection gap. Casing is mounted on carrier bracket and heat insulated from inside with gypsum layer. Pyrotechnic cartridge is located inside casing and receiver is formed above said cartridge and closed with cover, where igniter is located. Cover is formed with concentrically arranged discharge through openings oriented into cooling cylinder. Casing is equipped with transverse pins, one of said pins being rigidly connected to rocker arm carrying rod-type stopper, which may be selectively aligned with bracket pole openings for angular positioning of apparatus longitudinal axis. Temperature of aerosol mixture at apparatus discharge cut does not exceed 260 C. Apparatus provides for production of gas-aerosol fire extinguishing mixture flow generated due to burning of pyrotechnic compound in cartridge and injected immediately into volume to be protected from fire. EFFECT: wider operational capabilities and increased mobility in localizing fire zone and suppressing fire. 2 dwg
