LIQUID FLOW EJECTOR-TYPE SPREADER BY KOCHETOV Russian patent published in 2015 - IPC B05B1/26 

FIELD: machine building.

SUBSTANCE: in an ejector-type liquid flow spreader for a nozzle, a liquid flow spreader is fixed to the end face surface of a captive nut axisymmetrically to a casing. The spreader consists of three coaxially set pyramidal shells in the form of generating grids: inner, intermediate and outer ones. Each of the shells comprises a wire frame from two bases of square shape and lateral edges of a truncated pyramidal surface. The outer shell is fixed to the casing by the bigger base. The second base of the shell, the smaller one, is simultaneously the bigger base of the intermediate shell with lateral edges. The smaller base of the intermediate shell is simultaneously the bigger base of the inner shell with smaller base. The generating grids in the form of truncated pyramidal surfaces are arranged so that all their vertices lay on the axis coinciding with the casing axis. The direction of the vertices of the outer and the inner generating grids is the same. The vertex of the intermediate generating grid is counter directed in relation to the vertices of the outer and the inner generating grids to the side of a throttling orifice with a jet.

EFFECT: higher efficiency of liquid atomising.
