KOCHETOV COMPLEX ATOMISER Russian patent published in 2018 - IPC A62C31/02 

FIELD: technological processes; spraying.

SUBSTANCE: invention relates to spraying of fluids and can be used in fire fighting, agriculture, in chemical industry etc. This is achieved by the fact that in a complex nozzle for spraying liquids containing a hollow housing with a jet and a central core, the housing is provided with a channel for liquid supplying and contains a coaxial, rigidly coupled with housing bushing with a nozzle fixed in its lower part and made in the form of a cylindrical two-stage, top cylindrical step of which is thread-jointed to a coaxial central core having a central hole, and installed with annular gap relative to cylindrical bushing inner surface, wherein the annular gap is connected to at least three radial channels formed in a two-stage bushing connecting it to an annular cavity formed by the inner surface of the bushing and the outer surface of the upper cylindrical step, wherein annular cavity is connected with housing fluid supply channel, to the central core, in its lower part, a diffuser is rigidly connected, made in the form of flattened cone coaxial with the central hole of the core, and attached by its upper base to the base of the cylinder of the central core, and splitter is attached to flattened cone lower base by means of at least three pins, which is made in form of round end plate which edges are bent towards annular gap, and flattened cone on outer side surface there are helical grooves.

EFFECT: high efficiency of liquid fine spraying.
