KOCHETOV SWIRL ATOMIZER Russian patent published in 2018 - IPC A62C31/02 

FIELD: devices for spraying of liquids.

SUBSTANCE: invention relates to equipment for liquid atomization and can be used in fire fighting, agriculture, chemical industry and heat power engineering. Nozzle is provided comprising a hollow cylindrical body consisting of a cylindrical part with an external thread for connection to a distributor pipe fitting for the supply of liquid and internal thread for connection with the dissector by means of a disk and a rigidly connected ring through a circular plate in which a groove is made in the Archimedes' spiral, having a direction of twist coinciding with the direction of the twist of the swirl fluid flow located with a clearance relative to the inner cylindrical surface of the body and fixed in its lower part by, rigidly attached to it, a circular plate with a lower screw having a head made in the form of a conical fairing, the swirler being in the form of a sleeve with a screw outer thread with a large pitch of the trapezoidal profile and an internal thread, which includes the threaded part of the conical fairing in the upper part of the swirler, and the cylindrical chamber serves to supply liquid, but coaxially with the lower screw, a nozzle is attached to its head with a conical fairing in the form of a perforated conical socket, the tip of which is facing the conical fairing of the lower screw.

EFFECT: technical result is an increase in the efficiency of finely dispersed liquid spraying.
