KOCHETOV'S SWIRL ATOMISER Russian patent published in 2013 - IPC B05B1/34 B05B1/26 

FIELD: process engineering.

SUBSTANCE: invention relates to fluid sprayers and may be used in machine building, chemical and food industries. Screw is inserted into casing to make cylindrical chamber above said screw and aligned with diffuser and communicated therewith. Solid screw outer surface is composed of two connected surfaces. One of said surfaces represents, at least, single-thread helical groove with LH or RH thread located inside said casing. Second smooth surface represents a body of revolution axisymmetrically connected with spraying disc located perpendicular to casing axis to extend beyond casing bottom end. Both straight line and n-order curve may make a generating line of said surface.

EFFECT: higher efficiency and simplified design.
