KOCHETOV'S SPRAYER Russian patent published in 2011 - IPC A62C31/00 

FIELD: process engineering.

SUBSTANCE: invention relates to spraying of fluids and may be used in fire fighting, agriculture, etc. Proposed sprayer comprises hollow case with nozzle and central core. Note here that casing incorporates fluid feed channel and sleeve rigidly fixed aligned therewith that has nozzle secured at its bottom part. Said nozzle is made up of cylindrical two-step sleeve with top cylindrical step screwed on central core made up of cylindrical part and hollow cone aligned therewith arranged with circular clearance with respect to cylindrical 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 communicates with fluid feed channel. Sprayer is attached to cone bottom and made up of face round plate with edges bent toward circular clearance between nozzle and hollow cone. Note also that cone lateral surface has, at least, two lines of cylindrical throttling bores with their 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.
