Abstract
An air assisted spray nozzle assembly adapted for more efficiently producing a full cone spray distribution with finely atomized particles distributed throughout the conical spray pattern. The spray nozzle assembly includes a nozzle body having a liquid passage communicating with the pressurized liquid supply and at least one air passage communicating with a pressurized air supply. An air cap is disposed at a downstream end of the body which includes an impingement surface against which liquid is impinged and directed radially outwardly, an expansion chamber area about the impingement surface into which radially directed liquid is further broken down and atomized by a pressurized air stream, and a plurality of circumferentially spaced axial flow passages disposed about the impingement surface and each communicating between the expansion chamber and an angularly oriented discharge orifice such that the air cap is effective for discharging a plurality of atomized liquid flow streams in an outwardly expanding conical spray pattern.
