PNEUMATIC SPRAYER (VERSIONS) Russian patent published in 2014 - IPC B05B7/08 

FIELD: power engineering.

SUBSTANCE: pneumatic atomiser annular slotted gas nozzle is arranged at diffuser edge and features conical shape with taper angle of 60-150 degrees. Atomiser inner annular gas chamber incorporates extra two opposed nozzles. Axes of nozzles cross so that the angle between the axis of every nozzle and mirror axis of pneumatic atomiser varies from 30 to 90 degrees. Total area of the nozzles outlet cross-sections makes 0.3-1.0 of that of atomiser annular slotted gas nozzle. In compliance with second version, said atomiser annular slotted gas nozzle is arranged at diffuser edge and features conical shape with taper angle of 60-150 degrees and outlet cross-section of variable area over annulus perimeter.
