Abstract
An improved spray head for a nozzle for atomizing a liquid with a gas has an open inner end to receive the gas and liquid, a cylindrical medial portion defining a mixing chamber for creating a liquid-gas mixture, and an outer end wall that has a plurality of orifices arranged in a spaced circular orientation about the longitudinal axis of the mixing chamber. Each orifice defines a flow axis which is directed toward a linear target located a predetermined distance from the spray head for atomizing and directing a respective portion of the liquid-gas mixture onto the linear target in an approximately planar, flat fan spray pattern. A liquid atomizer is coupled in fluid communication between an inlet conduit for the liquid and the mixing chamber for atomizing the liquid discharged into the mixing chamber and creating the liquid-gas mixture.
