The invention relates to the atomization of liquids and solutions and can be applied in engine, chemical and food industries.

The closest technical solution to the claimed object is a fuel injector according to the patent of Russian Federation №2499634, F02 7/24, comprising a housing with a chamber into which is pressed the auger, and in the bottom of the case is made of throttle opening, and in the upper part fitting with a cylindrical bore, a diffuser and gasket (prototype).

A disadvantage of the known acoustic nozzle is that it does not provide a high degree of spray.

The technical result - improving the efficiency of spraying.

This is achieved in that in a centrifugal atomizer, comprising a housing into which is pressed the auger, and a nozzle for supplying a fluid, the housing consists of two coaxially interconnected, cylindrical sleeves: sleeves of larger diameter and a sleeve of smaller diameter, and the inside sleeve of smaller diameter, coaxially to it, is screw rigidly connected with its inner surface, for example pressed in, wherein the outer surface of the screw is a screw groove, and the inside of the auger is made of at least two concentrically arranged on circles, the number of through holes, thus in each row is made at least three holes, � of magnitude of the diameters of the holes decreases from the screw axis to the peripheral holes but in the sleeve of larger diameter, coaxially to it, is fitting rigidly fixed therein, for example by threaded connection, through a sealing gasket within the fitting is cylindrical coaxial bore passing into asymmetrically located diffuser, which is connected with the cylindrical chamber formed by the inner surface of the sleeve of smaller diameter, and the end surface of the screw and the inside of the screw, coaxially and symmetrically to him, fixed rod, one end of which is flush with its end surface facing the nozzle, and the other, free end of the rod, perpendicular to its axis is fixed, at least two, evenly spaced along the length of the rod disk, the diameter of which increases toward the free end of the rod and equally spaced along the length of the rod disks, the diameter of which increases toward the free end of the rod is made perforated.

Centrifugal atomizer consists of a casing consisting of two coaxially interconnected, cylindrical sleeves: sleeves 5 of larger diameter and the sleeve 4 of smaller diameter. Inside the sleeve 4 of smaller diameter, coaxially to it, 1 is a screw rigidly connected with its inner surface, for example�EP pressed into her. The outer surface of the auger 1 is a helical groove on the right (or left) cuts. Thus between the inner surface of the sleeve 4 of smaller diameter and the outer surface of the screw 1 is formed by a helical external cavity 3 of the screw 1.

In the sleeve 5 of larger diameter, coaxially to it, is a sleeve 7 rigidly fixed therein, for example by threaded connection, through a sealing gasket 6. Inside the fitting 7 is cylindrical coaxial bore 8 passing into asymmetrically located diffuser 9, which is connected with the cylindrical chamber 10 formed by the inner surface of the sleeve 4 of smaller diameter, and the end surface of the screw 1.

In the pipe 1 is made of one Central through hole 2, and at least two concentrically arranged on circles, the number of through holes 11 in each row is made at least three holes. The magnitude of the diameters of the holes decreases from the center hole 2 towards the periphery, in order at the beginning of the torch atomized stream of liquid had the highest rate.

Inside of the screw 1 is made of at least two concentrically arranged on circles, the number of through holes 11 in each row is made at least three holes, and sizes of diameters of the holes decreases from the axis of the screw 1 to the peripheral from�erstem 11.

Inside of the screw 1, coaxially and symmetrically to it, fixed to the rod 13, one end of which is flush with its end surface facing to the fitting 7, and the other, free end of the rod, perpendicular to its axis is fixed, at least two, evenly spaced along the length of the rod 13 of the disk 12, the diameter of which increases toward the free end of the rod 13.

Possible that equally spaced along the length of the rod 13 of the disks 12, the diameter of which increases toward the free end of the rod 2 is made perforated.

Centrifugal atomizer for atomization of liquids is as follows.

Liquid is supplied along the cylindrical hole 8 of the nozzle 7 in the diffuser 9, and from there into the chamber 10 from which is supplied under pressure simultaneously in two directions: first screw in the external cavity of the screw 1, forming the outer rotating fluid flow, and secondly - in peripheral throttling holes 11, forming a continuous stream.

At the exit of the nozzle there are two fluid flow, one flow, rotating turbulent type and the other a solid, which depending on pressure and geometry can be both laminar and turbulent, and that communicates serially arranged along the length of the rod 13 of the wheels 12, diameters to�which increases towards the free end of the rod 2.

In the interaction of the rotating and continuous flow at the nozzle outlet there is an additional fragmentation of liquid droplets due to their impact on the disks 12 in these liquid streams.
