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

FIELD: machine building.

SUBSTANCE: in liquid sprayer comprising a hollow cylindrical casing connected to a nozzle where orifice holes are made, the hollow casing consists of a cylindrical part with external thread to be coupled to the fitting of a distributing pipeline supplying liquid, and of two hollow cylinder-conical belts coupled sequentially and set coaxial to it, a nozzle in the form of a cup is fixed in the lower part of the casing coaxially to it, the cup bottom is provided with vertical and inclined orifice holes at an angle of 45° to the nozzle axis, the casing's cylindrical belt is provided with at least one row of radial holes with their axes being placed in the plane perpendicular to the casing axis plane, the number of holes in each row amounts to at least three: Casing and nozzle make several aligned inner chambers: cylindrical ones and a conical chamber set between them, one of the cylindrical chambers is used to supply liquid to be sprayed, and the conical chamber and the cylindrical one are expansion chambers. In central part of the nozzle coaxially with it a rod is secured with disk in the rod bottom part, secured on it perpendicular to its axis, against output cross-sections of the orifice holes of the nozzle, and in top part of the rod a strainer is secured located in the ring clearance between the cylindrical part of the casing and rod.

EFFECT: higher efficiency of fine liquid spraying.
