METHODS AND SYSTEMS FOR DELIVERING FLUID THROUGH HORNS FOR APPLYING MULTIPLE COMPONENT MATERIAL

摘要

Embodiments of a spray gun incorporating techniques for delivering a spray fluid between, next to, or inside of horn holes of an air atomization cap are provided. In accordance with certain embodiments, the spray gun includes a fluid delivery tip assembly. The spray gun also includes an air atomization cap disposed coaxially around the fluid delivery tip assembly, wherein the air atomization cap comprises one or more shaping air horns configured to deliver shaping air, and each shaping air horn comprises a first spray fluid passage configured to deliver a first spray fluid between, next to, or inside of one or more shaping air streams from the shaping air horn. The spray gun also includes a second spray fluid passage configured to deliver a second spray fluid to a fluid tip exit of the fluid delivery tip assembly.
