SPRAY NOZZLE, SPRAYER, SET OF SPRAY NOZZLES AND METHOD OF APPLYING FLUID MEDIUM Russian patent published in 2020 - IPC B05B1/06 

FIELD: technological processes.

SUBSTANCE: invention relates to devices, means and methods for spraying fluids, for example, stored under pressure in a vessel, in particular, to a spray nozzle, which can be used for fine dispersion of fluid medium on surface. Spraying nozzle comprising: a body with a cavity and a through hole communicating with the cavity and on the outlet of which there is an oval-shaped nozzle with chamfered walls diverging towards the outlet of the sprayed medium, wherein through hole is made with smooth continuous transition, which continues along whole length of through hole from round cross section to oval cross section, wherein transition contour is formed by various non-uniform contours for two intersecting planes, which intersection line coincides with central axis of through hole, wherein said intersecting planes pass through oval large and small axes and transition contour corresponds to Vitoshinsky circuit for each of oval major and minor axes.

EFFECT: technical result is improved quality of application of sprayed fluid medium on processed surface.
