<p>An internal mix air spray nozzle (90) for spraying fluent materials is comprised of a unitary one piece body (100) having a fluid material delivery bord extending therethrough and defining an air and fluid mixing chamber (122), a spray orifice (92) at the downstream end of the chamber, and a plurality of circumferentially spaced air orifices (126) inclined in the downstream direction into the chamber for introducing air into the fluid material and for causing the material to be emitted from the orifice as an atomized spray. The fluid supply passage, the air supply passages (126), the spray orifice (92) and the pressures of the air and fluid are correlated to produce a properly atomized spray of uniform spray density especially well suited for the spraying of heavily leaden and viscous materials such as stucco and the like. <IMAGE></p> |
