KOCHETOV'S SWIRL INJECTOR Russian patent published in 2015 - IPC B05B1/26 F23D11/04 

FIELD: machine building.

SUBSTANCE: proposed sprayer comprises casing with auger pressed therein and fluid feed union. Said casing consists of two aligned and coupled cylindrical sleeves: large diameter sleeves and small diameter sleeves. In the small diameter sleeve coaxially with it an auger is located, it is rigidly connected with its internal surface, at that the external surface of the auger is helical groove, and inside the auger at least two rows of through holes are made concentrically along circles. In each row at least three holes are made, and diameters of holes decrease from the auger axis to peripheral holes, and in the large diameter sleeve coaxially with it a union is installed, it is rigidly secured in it via the sealing gasket, at that inside the union a cylindrical hole is made coaxially, passing to an axially symmetrically located diffuser, which is connected to a cylindrical chamber formed by the inner surface of the sleeve of smaller diameter, and the end surface of the auger; and inside the auger coaxially and axisymmetrically with it a rod is secured, its one end is located flush with its end face looking on the union, and at the other free end of the rod at right angle to its axis at least two uniformly located along the rod length disks are installed, their diameters increase towards free end of the rod. The disks uniformly installed along the rod length and having diameters increasing towards free end of the rod are made perforated.

EFFECT: higher efficiency of spraying.
