  • Patent number: 4504014
    Abstract: A device (10) for atomizing a liquid is disclosed. The device (10) includes a sprayhead (14) receiving blown air through conduit (26) from boom (12). The air flows over wing 44 to create a region of reduced pressure within rectangular opening (64). A single stream of liquid is projected into opening (64) from where it flows over the secondary wing to trailing edge (54) for breakup and atomization within the vortex and turbulent flow following wing (44). Sprayhead (14) has a pair of elliptical nozzles (30, 32) superimposed on and orthogonally oriented with respect to one another to provide a proper projection pattern.
