ABSTRACT:
An air-assisted sprayer comprises a platform, an air reservoir, a fluid reservoir, a spray cap and a dual flow valve. The air reservoir extends through the platform and is configured to receive a source of pressurized air. The fluid reservoir extends through the platform to intersect the air reservoir, and is configured to receive a source of pressurized fluid. The spray cap is configured to receive pressurized air from the air reservoir and pressurized fluid from the fluid reservoir to discharge a stream of atomized fluid from the platform. The dual flow valve is positioned within the platform to intersect the air reservoir and the fluid reservoir to simultaneously vary volumetric flow rates of the pressurized air and the pressurized fluid over a range.
