SWIRL ATOMIZER Russian patent published in 2018 - IPC B05B1/26 B05B1/34 F23D11/04 

FIELD: technological processes.

SUBSTANCE: invention relates to fluid sprayers and may be used in machine building, chemical and food industries. Swirl atomizer comprises case with screw aligned in the case bottom section, and located in case upper part union with cylindrical hole for fluid supply connected with diffuser, axially symmetric to case and union. Screw is pressed into the case to make cylindrical chamber above said screw and aligned with the diffuser and communicated therewith. Solid screw outer surface is composed two connected surfaces, one of which is at least single-threaded groove with a right or left thread and is located inside the body, and the second surface is made smooth in the form of body of rotation. Screw is axisymmetrically connected with spraying disk 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. Surface of the spraying disc extending beyond the casing bottom end is made bent toward the lower part of the case and has radial cuts on the peripheral part alternating with the continuous part of the surface of the spraying disc.

EFFECT: invention allows to increase the spraying efficiency of liquid.
