CENTIFUGAL SWIRL ATOMISER OF KOCHSTAR TYPE Russian patent published in 2014 - IPC A62C31/02 

FIELD: machine building.

SUBSTANCE: centrifugal swirl atomiser comprises a casing, a coupling nut, an insert with tangential channels tapering downstream the flow, a swirling chamber, a nozzle and a disk adjoining the insert end face on the side of the tangential channels, the insert and the disk are produced from metal ceramics, lead-in edges of the tangential channels are rounded, a central hole is made in the end face surface of the coupling nut axisymmetrically to the casing and consists of a cylindrical part and a conical part, the insert has at least three tangential channels set in the plane perpendicular to the casing plane as well as the swirling chamber connected to the tangential channels, an orifice hole coaxial to the casing and set in the lower part of the insert, and a disk adjoining the insert end face on the side of the tangential channels perpendicular to the casing axis, a plate sprayer is attached to the end face of the coupling nut axisymmetrically to the casing and consists of at least two plates perpendicular to the casing axis and parallel to each other, one of the plates, the first plate, is provided with a central hole and the second plate is solid and is attached to the first one by at least three fastening elements including a screw and spacing calibrated washers installed between the plates as well as between the end face of the coupling nut and the first plate, the second solid plate of the plate sprayer is perforated and convex towards the end face of the coupling 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.
