KOCHETOV'S ATOMISER Russian patent published in 2015 - IPC A62C31/02 

FIELD: machine building.

SUBSTANCE: in atomiser containing a hollow casing with nozzle and central core, the casing is made with liquid supply channel, and has bushing coaxial and rigidly connected with the casing with bottom nozzle, made as cylindrical two-step bushing, top cylindrical step is connected by thread connection with the central core installed with ring clearance relatively to the internal surface of the cylindrical bushing and comprising cylindrical part with secured coaxially with it in bottom part by means of the pin, pressed in the nozzle and rigidly connected with the cone baffle, having throttle holes, which axes are located perpendicularly to the cone surface creating the baffle, and ring clearance is connected with at least three radial channels made in the two-step bushing connecting its with the ring cavity created by the internal surface of the bushing and external surface of the cylindrical step, at that the ring cavity is connected with the casing channel for liquid supply. On the side surface of the cylindrical part of the central core, in its bottom part connected with the cone baffle at least two rows of the cylindrical throttling holes are made with axes in planes perpendicular to the core axis, and in each row at least three holes are made. Axes of the throttling holes of the same row are displaced relatively to axes of the throttling holes of the next row by angle in range 15÷60°, to the free end face of the cone baffle with the throttling holes which axes are perpendicular to its cone surface the perforated sprayer is rigidly connected, it is made as hemispherical enclosure. Perforation is made by rows, the throttling hole dimensions decrease from the diametral layers of the hemi-sphere towards to its peripheral layers.

EFFECT: higher efficiency of fine liquid spraying.
