Abstract
A spray nozzle assembly including a hollow nozzle body having an air inlet orifice through which a pressurized air stream is directed into the body, a liquid inlet orifice through which a pressurized liquid flow stream is directed into the body, an impingement member disposed within the body for breaking up the liquid and air flow streams and preatomizing the liquid, and a nozzle tip mounted at the discharge end of the body defining a discharge orifice. The nozzle tip is formed with a deflector flange downstream of the discharge orifice in transverse relation to the direction of travel of the preatomized liquid passing through the discharge orifice and the deflector flange is formed with a cup shaped recess in axial alignment with the discharge orifice into which the preatomized liquid is directed from the discharge orifice for causing further breakdown and atomization of the liquid which is thereupon directed by the deflector flange transversely in a substantially flat spray pattern. Alternative embodiment of spray tips with cup shaped deflectors are disclosed. The impingement member preferably is removably mounted within the nozzle body so as to enable the nozzle to be used in an…
