| 20110147491 | INTERNAL MIX AIR ATOMIZING SPRAY NOZZLE ASSEMBLY - An internal mix air atomizing spray nozzle assembly comprising a nozzle body with a liquid discharge orifice defined by a relatively small diameter nose portion and an air cap having a central opening disposed in surrounding relation to the nose portion for defining an annular pressurized air passageway surrounding the liquid discharge orifice. To facilitate intermixing of liquid particles discharging from the air cap discharge orifices and for reducing negative pressures between the discharging flow streams, the air cap has an internal mixing chamber larger in diameter than the annular pressurized air discharge orifice and is formed with a plurality of circumferentially spaced discharge orifices oriented in skewed relation to a central axis of the nozzle. In the illustrated embodiment, the internal mixing chamber is defined by a cylindrical cavity within the air cap and a separate insert mounted in an upstream end of the air cap. | 06-23-2011 |
