Abstract

The present invention pertains to the field of fire-fighting techniques and relates to a foam generator comprising a cylindrical body with flanges at the ends thereof, wherein one of said flanges comprises a nozzle for supplying an aqueous solution of a foaming agent. The side surface of the body also includes a radial duct for supplying air. The body includes a cylindrical mixing chamber that widens at the outlet as well as a conical diffuser. The mixing chamber is arranged so that its longitudinal axis is offset relative to the longitudinal axis of the nozzle. A load is attached to the mixing chamber so as to leave a gap relative to the body. In a first embodiment, the diffuser is connected by its lager base to the flange of the body which is opposite the nozzle. In a second embodiment, the mixing chamber is mounted inside the body using an additional support in the shape of a thin-wall truncated cone. It is thus possible to increase the pressure conversion ratio.

Intended use.

In general, the proposed generator, as shown in the test, produces foam with a low waste of at least 3-3.4. Foam has a one-piece small-scale friction unit> with a diameter of a separate element less than 1 mm. This structure ensures that the stability is stable, since it is vented, it is also exposed to pressure, and it is not subject to pressure. At the same time, the generator has a high pressure coefficient (not less than 30%), since the pressure at the outlet is equal to 9 atm.
