KOCHETOV'S SWIRL INJECTOR Russian patent published in 2015 - IPC B05B1/26 B05B1/34 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 an union is installed, it is rigidly secured in it via the sealing gasket. In the union coaxially cylindrical hole is made, it transits in axisymmetric diffuser connected with the cylindrical chamber created by internal surface of the small diameter sleeve, and end face 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. On the free end of the rod the perforated sprayer is installed made in form of spherical segment, its concave part looks towards the disk last through the rod length, and to the peripheral part of the spherical segment the perforated cone shell is secured, the another part is rigidly connected with the end face of the cylindrical sleeve with small diameter of the injector casing.

EFFECT: higher efficiency of spraying.
