KOCHETOV'S SWIRL ATOMISER Russian patent published in 2014 - IPC B05B1/26 B05B1/34 F23D11/04 

FIELD: process engineering.

SUBSTANCE: invention relates to fluid sprayers and may be used in machine building, chemical and food industries. Swirl atomiser comprises case with screw aligned in the case bottom section. Case top part union has cylindrical fluid feed hole. The latter communicates with diffuser axially symmetric with case and union. Screw is inserted into case 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 surface is smooth and composed of the body of revolution connected in axial symmetry with sprayer disc arranged perpendicular to housing axis. Besides, it extends beyond the housing bottom. Both straight line and n-order curve may make a generating line of said surface. Sprayer disc surface extending beyond housing bottom end surface is bent towards housing bottom. It has radial cut-outs ate peripheral part to alternate with solid surface of sprayer disc.

EFFECT: higher efficiency of spraying.
