Abstract
The device () utilizes a standard reversible airless tip (). The air cap () is provided with four air passages () which aim radially inwardly at 45° from the centerline of the housing (). The passages () have a 12° angle from being perpendicular to the longitudinal axis () of the assembly (). The four jets () provided by these passages are guided by four channels () in the surface of the housing () (also having the 12° ramp angle) so as to guide the air flow to the center of the oval orifice () in the carbide (). Two pairs of opposing air jets () are also provided in the air cap () directed perpendicularly to the fan () of paint or other atomized material and these jets () are angled at about 20.5° relative to the plane that is perpendicular to the longitudinal axis () of the assembly (). Each pair is directed at one another and is spaced laterally from the longitudinal axis () to help in removing tails from the pattern.
