Abstract
A spray gun apparatus having air passages for the atomization of liquid passing through a liquid outlet orifice, and having air passages for directing air flow against the atomized particles emitting from the spray orifice, wherein the atomizing air passages are separated from the fan air passages, and an adjustable control valve selectively controls the volume of air through the fan air passages. The spray apparatus has an air spray nozzle including a spray nozzle concentrically fitted into an air cap, both parts being precisely aligned along a common axis; the air cap includes a contoured groove for smoothly directing air flow to fan air orifices.
