PNEUMATIC VORTEX INJECTOR Russian patent published in 2017 - IPC B05B7/10 

FIELD: machine engineering.

SUBSTANCE: pneumatic vortex nozzle comprises a body into which a screw is press-fitted, and elements for supply of liquid and air. The body consists of two coaxial interconnected cylindrical bushings: the bushing of larger diameter and the bushing of smaller diameter. A diffuser is attached to the end part of the bushing body of smaller diameter, on which cut there is a liquid flow splitter made in the form of a perforated ring coaxial with the diffuser. An auger is located inside bushing of smaller diameter coaxially relative to it and rigidly connected with its inner surface and pressed therein. The shaped bushing which inner surface is formed by conical and cylindrical surfaces is rigidly secured in the larger diameter bushing by means of threaded joint through a sealing gasket. A conical funnel is attached to liquid flow splitter made in the form of a perforated ring coaxial with the diffuser. A smaller base of the funnel truncated conical surface is connected to inner surface of the splitter opening.

EFFECT: improved efficiency of liquid spraying.
