KOCHETOV'S CENTRIFUGAL VORTEX NOZZLE Russian patent published in 2017 - IPC A62C31/02 

FIELD: machine engineering.

SUBSTANCE: centrifugal vortex nozzle contains chassis, cap nut, insert with tapered thread of tangential channels, swirling chamber, nozzle and disc adjacent to the end of the liner by tangential channels. The insert and disk are made out of metal-ceramics. The input edges of the tangential channels are rounded. In the face of the sleeve nut, axisymmetric to the body, the central hole is made, consisting of the cylindrical part and of the conical part. The liner has tangential channels, which are situated in the plane perpendicular to the axis of the chassis, as well as the swirling chamber connected with tangential channels. Coaxial housing orifice is arranged in the lower part of the insert. To the end surface of the union nut, axially symmetric body, secured liquid flow divider, designed as a perforated conical shell with a base, fastened with screws on the end face of the union nut. The top of the conical mantle surface directed away from the fluid flow swirler. The spherical perforated segment is fixed in the lower part of the dissector in such a way that the apex of the conical shell coincides with the center of the spherical surface of the perforated segment.

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