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

FIELD: devices for spraying or atomizing liquids.

SUBSTANCE: invention relates to devices for liquids, solutions spraying. Swirl atomizer contains a body with a swirl chamber and a nozzle. Body is made in the form of a supply fitting with a central hole and rigidly connected to it and a coaxial cylindrical sleeve with an internal thread and an expansion chamber coaxial to the housing. Nozzle made up of upturned cup is aligned with bottom of said casing and threaded to said sleeve. Cup bottom is provided with fluid flow turbulence swirler with, at least, two inclined feed cylinder holes inclined to the nozzle axis and made in nozzle face surface, where also a central cylindrical throttle opening is made connected to the nozzle mixing chamber, in series connected to the diffuser outlet chamber. Divider is installed in the diffuser outlet chamber in the form of at least three spokes, each of which is fixed at one end to the outer surface of the diffuser outlet chamber, perpendicular to the surface forming it, and the other in the surface of the body of revolution, whose axis coincides with the axis of the diffuser outlet chamber, and the body of revolution itself is located in the lower part behind the cutoff of the diffuser outlet chamber. Diffuser is attached to the end surface of the cylindrical sleeve, which is coaxial with the body, in coaxial relation to the diffuser chamber, the cutoff surface of which lies in a plane that is below the surface of the body of the divider revolution, and the surface of the body of revolution is made in the form of an ellipsoid whose minor axis is axisymmetric to the axis of the diffuser outlet chamber.

EFFECT: technical result of invention is increasing spraying efficiency by spray cone increasing.
