ABSTRACT OF THE DISCLOSURE An air assisted spray nozzle having a nozzle body formed with an elongated mixing and atomizing chamber having an air inlet orifice communicating with one end of the chamber, a liquid inlet orifice communicating with a side of the chamber, and a nozzle tip having a discharge orifice located at the end of the chamber opposite the air inlet orifice. Transversely directed streams of pressurized air and liquid enter and converge in the mixing and atomization chamber of the nozzle body causing preliminary atomization of the liquid, which is thereupon directed under the force of the high velocity air stream out the discharge orifice and against a deflector flange of the nozzle tip which further atomizes the liquid and directs it into A well-defined flat fan spray pattern with uniform distribution and liquid particle size. To enhance preliminary atomization, the mixing and atomizing chamber has an inwardly extending liquid impingement post in diametrically opposed relation to the liquid inlet orifice, and to facilitate further atomization and controlled direction of the discharging spray the deflector flange defines an arcuate shaped guide surface which is substantially wider than the width of the discharge orifice and has a terminal lip transversely offset from the discharge orifice.
