CENTRIFUGAL SWIRL ATOMISER OF KOCHSTAR TYPE Russian patent published in 2015 - IPC A62C31/02 

FIELD: machine building.

SUBSTANCE: centrifugal swirl atomiser containing casing, captive nut, insert with tangential channels tapering along the flow, vortex chamber, nozzle and disk. The insert and disk are made out of metal-ceramics. In the end surface of the captive nut a central hole is made axisymmetric to the casing. The insert has tangential channels located in the plane perpendicular to the casing axis, and vortex chamber. Throttle hole is located in the bottom part of the insert. The disk is adjacent to end face of the insert at side of the tangential channels perpendicular to the casing axis. To the end face of the captive nut the plate sprayer is secured, it contains plates at right angle to the casing axis and parallel with each other. It has central hole, and second plate is made continuous and is secured to the first by means of the fasteners. Second continuous plate is made perforated and convex towards end face of the captive nut.

EFFECT: higher efficiency of liquid atomising due to reduced hydraulic resistance of the atomiser at keeping the flow characteristics, provision for homogeneous mixing with the inflow medium.
