KOCHETOV'S RADIAL-FLOW SPRAYER Russian patent published in 2012 - IPC F23D11/04 B05B1/34 

FIELD: machine building.

SUBSTANCE: proposed sprayer comprises casing with auger pressed therein and fluid feed union. Said casing consists of two aligned and coupled cylindrical sleeves. larger-diameter and smaller-diameter sleeves. Note here that smaller-diameter auger is fitted aligned inside said sleeve and rigidly coupled with its inner surface, for example, press-fitted therein. Note also that auger outer surface represents a screw groove while one central through bore is made inside said auger and, at least, two rows of through bores are arranged concentrically along the circumference. Note that every said row has, at least, three bores while bore diameters decrease from central bore to peripheral bores. Larger-diameter sleeve accommodates union rigidly secured therein, for example, by thread joint, via tight gasket. Mind that said union has cylindrical bore changing into axially symmetric diffuser communicated with cylindrical chamber formed by smaller-diameter sleeve inner surface and auger face surface.

EFFECT: higher efficiency of spraying.
