AIR-FOAM HOSE Russian patent published in 2012 - IPC A62C31/00 

FIELD: fire-fighting means.

SUBSTANCE: invention relates to fire-fighting equipment, namely, the constructions for production from an aqueous solution of foamgenerator of air-mechanical foam and direction of the combustion zone. Air-foam hose comprises a housing with a threaded-end connecting head and a nozzle. To the housing from one side a threaded-end connecting head is attached axisymmetrically, inside which there is a sealing cup for connecting the hose to the hose line, and nozzles from the other. In the housing there is a divider with a central throttling hole located axisymmetrically to the hose housing. Behind the divider in the housing at least three ejecting holes are made which are evenly spaced in a plane perpendicular to the axis of the housing. The nozzle comprises a hollow body in the form of a sphere, which has an inlet and outlet throttling element of a slot type, and the body is placed between the pipe connecting the die-cast housing of the hose with a nozzle and a clamp, fixing it so that the plane of the inlet of the housing is located perpendicular to the axis of symmetry of the hose. The inner and outer surfaces of the nozzle body are made spherical, with the inlet of nozzle hole is connected to the outlet throttling element through the inner spherical cavity of the housing.

EFFECT: increased efficiency of fire fighting.
