Abstract
A laminated array of pressure swirl atomizers forms spray plate that produces a fine mist or spray of liquid. The atomizers may be arrayed in a custom manner that may be made application specific for greater efficiency. The spray plate is typically formed of a plurality of laminated plates. In a preferred embodiment, a plate adjacent to a fluid reservoir provides an array of aperture sets, each aperture set having two or three apertures that allow liquid to pass from the pressurized reservoir through the first layer. The second plate provides a corresponding array of swirlers, each swirler providing at least two swirl feed ports to tangentially project liquid into the swirl chambers contained in a third plate. A fourth plate provides a corresponding array of discharge apertures, which release the liquid in an atomized state.
