Abstract
A spray device that includes a swirl atomizer and a source of pressurized liquid. The atomizer includes a housing that defines a tubular chamber having a side wall, a first end wall, and a second end wall that opposes the first end wall. The atomizer further includes a bleed outlet channel in the second end wall that is configured to bleed an excess liquid from the atomizer, and a spray outlet channel in the first end wall. The spray outlet channel is narrower than the bleed outlet channel. The side wall includes a first face and a second face that opposes the first face. A length of the chamber between the first end wall and the second end wall is at least twice a width of the chamber between the first face and the second face of the side wall.

- and
- a spray outlet channel in the first end wall, the spray outlet channel narrower than the bleed outlet channel;
- wherein the side wall includes a first face and a second face that opposes the first face, and
- wherein a length of the chamber between the first end wall and the second end wall is at least twice a width of the chamber between the first face and the second face of the side wall.
