Abstract
A spray nozzle assembly is provided. The spray nozzle assembly includes a nozzle body having a liquid passage that terminates in a nozzle body orifice. The spray nozzle assembly includes an impingement element having an impingement surface spaced from the nozzle body orifice. One or more air outlet orifices are disposed upstream of the impingement surface and oriented to discharge a substantially tubular curtain of air around the nozzle body orifice. An air cap defines a chamber extending around and downstream of the impingement surface. The air cap has a plurality of discharge orifices. At least one of the discharge orifices in the air cap has an associated nipple that is integrally connected to the air cap and extends the discharge orifice outwardly away from an outer face of the air cap.
