Abstract
Method and apparatus for providing an electrostatically charged, airless, round vortex spray of liquid in which spray pattern irregularities may be eliminated. In addition to a central nozzle for forming the round vortex spray there is provided an annular nozzle for forming an auxiliary air vortex which is imparted with whirling motion in a direction opposite to that of the round spray of liquid. The air flow rate for the auxiliary air vortex is set above a value at which spray pattern irregularities disappear. The hydrostatic pressure for the round spray ranges between 25 and 75 bars and the air pressure for the auxiliary air vortex ranges between three and one bar.
