Abstract:
1. A pressurized air assisted liquid spray nozzle assembly comprising: a liquid spray nozzle having a central liquid passage for coupling with a pressurized liquid supply and a discharge orifice at a downstream end for discharging a constant stream of liquid; an air guide mounted in surrounding relation to the downstream end of said liquid spray nozzle; an outer nozzle body disposed in surrounding relation to said air guide having a central opening coaxial with said liquid spray nozzle central liquid passage and discharge orifice; said air guide defining a first plurality of air passages for directing pressurized atomizing air in a radial direction transverse to liquid discharging from said liquid spray nozzle discharge orifice for interacting and atomizing the discharging liquid into liquid particles following discharge from said spray nozzle discharge orifice; and said air guide defining a second plurality of air passages for directing shaping air tangentially to liquid discharging from said liquid spray nozzle and atomized by said atomizing air following discharge from said spray nozzle discharge orifice for shaping the atomized liquid particles into a predetermined conical spray pattern.
