FIRE TRUCK AND FOAM GENERATOR Russian patent published in 2020 - IPC A62C27/00 A62C5/00 

FIELD: fire safety equipment.

SUBSTANCE: invention relates to fire-fighting equipment, namely, to fire-fighting ground vehicles for fire extinguishing of solid combustible materials (SCM) by means of foam fire extinguishing. Fire truck 1 comprises basic chassis, in body 2 of which there is a system for generating quick-setting compression foam, which, together with foam supply device to fire center, consists of modular units 3, 4, 5. Each modular unit 3–5 consists of cylinder 7 of foaming agent solution, of device for air supply in the form of cylinder 8 with compressed air, of cylinder 9 with compressed gas, of paired sleeves 10 of high pressure of sleeve line, of foam supply device to fire center made in the form of foam generator 11. Foam generator 11 comprises housing 24 with compression foam components supply via two sleeves 25, 26 with shutoff devices 21, 22, distribution nozzle 27 at housing inlet 24, cylindrical mixing chamber 28 under pressure of compression foam components, a set of foaming grids 29 and confuser 30 with convergent outlet channel changing into cylindrical barrel 31 of compression foam flow 32.

EFFECT: simplified system of compression foam supply from fire engine to fire center by means of creation of such scheme of supply of compression foam components and special design of foam generator, which make it possible to generate compression foam near fire center, including for use in extinguishing fires when supplying fire extinguishing agent (EA) to the twentieth and even to the thirtieth floor; possibility of using four fire-fighting modes.
