Abstract
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.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
136 words
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.
Claim 2
Dependent Claim
136 words
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.
Claim 3
Dependent Claim
32 words
The apparatus according to claim 1 wherein the outlet end of said first air chamber has a converging frusto-conical shape which terminates at a cylindrical duct, said duct leading to the atmosphere.
Claim 4
Dependent Claim
25 words
The apparatus according to claim 2 wherein said turbulence creating means comprises a V-shaped groove concentrically disposed in said outlet end about said central aperture.
Claim 5
Dependent Claim
19 words
The apparatus according to claim 1 wherein said second air chamber is annularly disposed about said first air chamber.
Claim 6
Dependent Claim
26 words
The apparatus according to claim 1 wherein each pattern adjusting nozzle is located in a nozzle ear which projects beyond the plane of said central aperture.
Claim 7
Dependent Claim
25 words
The apparatus according to claim 3 wherein said pattern adjusting plate is a ring configured to abut the outlet end of said second air chamber.
Claim 8
Dependent Claim
22 words
The apparatus according to claim 1 wherein said pattern adjusting plate has ports which may be movably aligned with pattern adjusting nozzles.
Claim 9
Dependent Claim
20 words
A apparatus according to claim 5 wherein two pattern adjusting nozzles are located on diagonally opposite sides of said aperture.
