KOCHETOV PNEUMATIC SPRAYER Russian patent published in 2018 - IPC A62C31/02 

FIELD: devices for spraying liquids.

SUBSTANCE: invention relates to spraying of fluids equipment and can be used in fire fighting, agriculture, chemical industry and heat power engineering. In the liquid atomizer comprising the hollow cylindrical housing connected to the nozzle, in which throttling openings are made, hollow housing consists of cylindrical part with outer thread for connection to the distribution pipeline union for the liquid supply and two in-series connected and coaxial to it hollow cylindrical and conical belts, and coaxially to the housing, in its lower part nozzle is fixed, made in the form of cup, in which bottom vertical and inclined throttling holes are made at an angle of 45 ° to the nozzle axis, and in the housing cylindrical belt, at least one row of radial holes is made, which axes lie in the perpendicular to the housing axis plane, at that, the number of holes in each row is equal to at least three, at that, among themselves the housing and nozzle form the several coaxial inner chambers: cylindrical ones and located between them conical chamber, wherein one of the cylindrical chambers serves to supply the liquid to be sprayed, and the conical and cylindrical chambers are expansion chambers, and in the nozzle central part, the air (gas) supplying tube is fixed coaxially to it, to one end of which, in its lower part, hollow disk is fixed with perforation facing the nozzle throttle openings outlet cross-sections.

EFFECT: higher efficiency of the liquid atomizing.
