Abstract: An electrostatic spray gun in which coating or other material is metered through an orifice adjustable in size to accommodate materials of various viscosities and consistencies and is thereafter atomized upon being injected as a conical fluid sheet into a central stream of high velocity air. Adjustment of the orifice and thus of the flow rate of the material is accomplished by rotating the spray head relative to the gun body. Further atomization of the material and development of the spray are produced by fluid streams exiting through an annular opening and other fluid orifices spaced around the spray outlet opening. The atomized particles are charged electrically by a rearwardly directed corona discharge established between a corona electrode supported on the spray head and an attractor ring positioned on the spray head in surrounding relation to the spray outlet opening.
