Abstract
An improved spray nozzle for use with air atomizable liquids wherein the spray pattern created by the atomizing nozzle may be adjusted from a circular pattern to a flat pattern or alternatively to an open oval, the open end facing in preselected directions, the adjustments being capable of occuring during the continuous operation of the nozzle. A pattern adjusting plate may be movably aligned with the pattern adjusting nozzles thereby creating the appropriate combination of pattern adjusting nozzles to create the desired pattern.
Claims8
A spray nozzle for use with air atomizable liquids comprising:
- a first air chamber having an outlet end;
- a reciprocably mounted fluid nozzle valve having a conical taper prenetrating said first air chamber and extending to and coaxially aligned with a central circular aperture in the outlet end of said first air chamber;
- means for delivering a liquid to said central aperture for atomization by air exiting said chamber through said aperture;
- integral means at said outlet end for creating turbulence in the air in said chamber;
- a second air chamber having an outlet end, at least two pattern adjusting nozzles disposed at the end of said second air chamber adjacent to the aperture of said first air chamber;
- and
- a pattern adjusting plate for selectively blocking said second air chamber from said pattern adjusting nozzles.
