Abstract
An air assisted spray nozzle assembly having an air cap effective for generating wide, flat spray patterns with improved liquid particle breakdown, utilizing relatively low air flow rates and pressures. The air cap includes a pair of longitudinally extending air passageways on opposite sides of a central liquid flow stream discharge orifice. The air flow passages each have a discharge orifice defined by a respective transverse deflector flange and a closely spaced inwardly tapered deflector surface which cooperate to deflect and guide pressurized air streams inwardly toward the discharging liquid flow stream for atomizing the liquid and for directing it into a well defined spray pattern.
