ACOUSTIC VORTEX NOZZLE Russian patent published in 2014 - IPC F23D11/34 B05B17/06 

FIELD: machine building.

SUBSTANCE: acoustic vortex nozzle comprises a body, elements for liquid and air supply, the body comprises two coaxial cylindrical bushings joined to each other: a bushing of larger diameter and a bushing of smaller diameter, at the same time inside the bushing of smaller diameter, coaxially to it, there is an auger, rigidly connected to its inner surface, besides, the outer surface of the auger is a helical groove, which forms with the inner surface of the bushing of smaller diameter the helical outer cavity, and inside the auger there is a hole with helical thread, connected with the tube for supply of liquid under pressure, and in the bushing of larger diameter coaxially to it there is a shaped bushing, the inner surface of which is formed by conical and cylindrical surfaces, and which is rigidly fixed in the bushing of larger diameter via a sealing gasket, having at least one throttling hole, and forming with the end surface of the auger and the inner surface of the bushing of smaller diameter - a cylindrical chamber, which by means of a channel is connected to a source of compressed air, and in the cylindrical cavity of the shaped bushing there is a free end of the tube for supply of the liquid, placed in the coaxial elastic ring, which with the sealing gasket forms a conical resonant chamber, at the same time the throttling hole performs the function of the "Helmholtz" resonator neck.

EFFECT: increased efficiency of liquid spraying.
