FIRE EXTINGUISHER SPRAYING NOZZLE Russian patent published in 2011 - IPC B05B17/08 

FIELD: process engineering.

SUBSTANCE: invention relates to firefighting equipment and may be used for producing sprayed jet in nozzles of fire extinguisher. Proposed nozzle comprises case and nozzle and connection branch pipe to feed fire-extinguishing substance. Fire-fighting substance flow coherent oscillation generator made up of, at least, two straight rods is arranged in said casing, between nozzle and connection branch pipe. Every said rod is arranged to locate rod lengthwise axis perpendicular to fire-extinguishing flow direction. Rod profile cross section has axis of symmetry. Rods are arranged in casing sequentially in direction of fire-extinguishing flow in different planes, relative to each other, at distance exceeding profile size along its axis of symmetry. Rod end sections are secured in casing walls.

EFFECT: simplified design, higher efficiency.
