<p>A nozzle for utilization on a spray gun operated for the spraying of pressurized liquids through an elliptical orifice, wherein pressurized air is utilized in conjunction with the invention to enable an improved quality spray at a lower liquid pressure. The nozzle has a pair of air jets on either side of the elliptical orifice, positioned in diametrically opposite equidistant locations, and respectively directed along axes which cause the air jet envelope to tangentially contact the orifice at a point outside the included angle formed by the fan-shaped spray pattern emitted from the orifice.</p> |
