KOCHETOV'S FLUID SPRAY NOZZLE Russian patent published in 2012 - IPC B05B1/14 

FIELD: process engineering.

SUBSTANCE: invention relates to spraying of fluids and may be used in firefighting, agriculture, etc. Nozzle case is provided with fluid feed channel and comprises coaxial sleeve secured thereto with nozzle secured at its bottom section. Said nozzle is made up of cylindrical two-step sleeve with upper step thread-jointed to central core. Said ore comprises cylindrical part and hollow case aligned therewith and fitted with annular clearance relative to sleeve inner surface. Said circular clearance is communicated with, at least, three radial channels made in said two-step sleeve to communicate with circular cavity formed by sleeve inner surface and top cylindrical step outer surface. Circular cavity is communicated with case fluid feed channel. Sprayer made up of end face round plate is screwed to cone bottom. Plate edges are bent toward annular clearance between nozzle and hollow cone. Cone side surface has, at least, two lines of cylindrical restricting openings with axes located in planes perpendicular to cone axis. Each line has, at least, three holes. Axes of aforesaid throttling holes of one line are displaced relative to those of the other lines through the angle varying from 15° to 60°.

EFFECT: higher efficiency of spraying.
