Abstract:
A spray device includes side-by-side spray tips that are spaced from one another at a distal end of the spray device. A first spray tip has a first fluid pathway defining a first flow area. The first fluid pathway has a first swirl chamber having an outer perimeter and flutes having inner ends that direct a first fluid into the outer perimeter of the first swirl chamber for rotating the first fluid in a circular pattern. A second spray tip has a second fluid pathway that defines a second flow area that is larger than the first flow area. The second fluid pathway has a second swirl chamber having an outer perimeter and flutes having inner ends that direct a second fluid into the outer perimeter of the second swirl chamber for rotating the second fluid in a circular pattern.
