Abstract: PROBLEM TO BE SOLVED: To provide an atomization apparatus capable of lessening the unevenness of the entire patterned region at the time of spraying and accordingly making the coating thickness distribution uniform in the coated face and easily forming a smooth coating free from disorder of the coating face in an air atomizing spray gun.
SOLUTION: The air cap is to be used in an air spray gun for atomization with compressed air and has a center air port composing a circular air port in the outer peripheral part of a center coating material jetting port, a pair of corner parts formed symmetrically in the outside of the center air port, and side air ports for forming spraying patterns by jetting air through the corner parts. In the air cap, the surface area of inlet parts of vertical holes formed in the respective corner parts and communicating with the side air ports is made smaller than the surface area of the side air ports. To make the inlet surface area narrower than the vertical hole surface area by narrowing the flow channel surface area, a bush is fitted or caulking is carried out in the circumference of the vertical hole inlets.
