CENTRIFUGAL VORTEX NOZZLE Russian patent published in 2008 - IPC F23D11/04 B05B1/34 

FIELD: mechanics.

SUBSTANCE: centrifugal vortex nozzle incorporates a casing with a chamber furnished with an auger furnished with an outer threaded groove. Note that the casing bottom is furnished with a throttling hole and its top is provided with a union with a cylindrical bore. In compliance with this invention, the auger inside features a threaded hole with the thread sense either mating or running opposite to that of the auger outer thread. Note also that the mixing chamber is arranged beneath the auger made up of cylindrical and taper parts. Note also that the aforesaid auger is rigidly linked with the T-shape throttling washer, its cylindrical end face part being provided with three inclined throttling holes with their axes are running tangentially to the chamber inner surface. Note also that the axial cylindrical part rigidly linked to the former is furnished with and axial throttling hole aligned with threaded hole arranged in the auger. Mind that the drag of throttling holes is selected depending upon the properties of liquid being sprayed and the required degree of liquid atomising. Note here that the auger is made in high-strength material, e.g. tungsten, or ruby, or carbide, or sapphire carbides.

EFFECT: higher efficiency of spraying.
