NOZZLE BY KOCHETOV FOR SPRAY OF LIQUIDS Russian patent published in 2014 - IPC A62C31/02 

FIELD: machine building.

SUBSTANCE: nozzle for spraying liquids comprises a hollow body with a nozzle and a central core, the body is made with a channel for supply of liquid and comprises a coaxial bushing rigidly fixed to the body with a nozzle fixed in its lower part, made in the form of a cylindrical double-staged bushing, the upper cylindrical stage of which is connected by means of a threaded joint with a central cylindrical core having a non-through inner central opening and installed with a circular gap relative to the inner surface of the cylindrical bushing, and the circular gap is connected at least with three radial channels, made in a double-staged bushing, connecting it with the circular cavity formed by an inner surface of the bushing and an outer surface of the upper cylindrical stage. Besides, the circular cavity is connected to the channel of the body for supply of liquid. At the same time in the lower part of the central cylindrical core there is a partition made with a hole, on which there is a hollow conical swirler. Besides, the conical shell of which is fixed on a circular collar, formed in the partition by a hole, and on the outer surface of the hollow conical swirler there is a helical thread.

EFFECT: higher efficiency of fine dispersed spraying of liquid.
