ATOMISER WITH HEMISPHERICAL SPREADER Russian patent published in 2015 - IPC A62C31/02 

FIELD: machine building.

SUBSTANCE: liquid atomiser comprises hollow case with nozzle and central core. Said case has fluid feed channel sleeve aligned and rigidly coupled therewith and made up of cylindrical two-step sleeve. Top cylindrical step of the latter is threaded to central core arranged with clearance relative to inner surface of cylindrical sleeve and made up of cylindrical section with ball segment fitted by the pin at its bottom and aligned therewith. Said ball segment has restricting holes with their axes locates along radii of spherical surface that form said ball segment while circular clearance is communicated with, at least, three radial channels made in two-step sleeve to communicate with circular chamber formed by inner surface of the sleeve and outer surface of top cylindrical sleeve. Note here that said circular chamber communicates with the case fluid feed channel. Note also that central core cylindrical section is provided with, at least, two rows of restricting bores are arranged concentrically along the circumference with their axes located in planes perpendicular to core axis. At least, three bores are made in every row. Note here that restricting bore axes in one row are shifted relative to those in the row by 15°-60°. To the bottom cylindrical part of the nozzle bushing with ball segment fitted by the pin coaxially with it in bottom part, having restricting holes a flow spreader is secured made in form of mesh diffuser, the large base of the truncated cone projects beyond the ball segment.

EFFECT: higher efficiency of fine liquid spraying.
