FIRE EXTINGUISHER Russian patent published in 1994 - IPC

FIELD: fire fighting. SUBSTANCE: fire extinguisher has case filled with combined fire-extinguishing liquid which has different density, compressed air source connected with top part of the case, siphon tube provided with inlet and outlet holes attached to cap of the case and a float provided with through radial channels and internal space mounted onto the tube. The tube is telescopic; float and stabilizer are mounted onto internal unit of the tube which are used for submerging the unit into liquid which has higher density. Cavity of the float is communicated with inlet hole of siphon tube. Float plays role of a weigher and mixer, as relation of quantities of liquids with different densities entering the siphon tube depends on depth of submergence of float into liquid which has higher density. EFFECT: improved efficiency. 2 dwg
