Abstract: Provided are nozzle assemblies and related methods for a spraying apparatus. The nozzle assembly includes a fluid side wall defining a fluid passageway that extends longitudinally along a fluid axis and terminates in a fluid aperture; an air cap side wall extending around the fluid side wall and partially defining an air passageway that terminates in an atomizing aperture adjacent the fluid aperture. A pair of diametrically opposed air horns protrude past the fluid aperture from the air cap side wall and define respective air horn cavities in communication with the air passageway, each air horn having an external surface and a fan control aperture extending along a fan control axis through the external surface to flow air against a fluid stream discharged from the fluid aperture. The fan control aperture has a certain aperture shape defined along a reference plane perpendicular to the fan control axis, and for each air horn, a baffle projects into a volumetric shape defined by extruding the certain aperture shape outwardly along the fan control axis. The baffle modifies the shaping air jets between the fan control apertures and the atomized fluid stream to provide a refined spray pattern.

Abstract: Provided are nozzle assemblies for a spraying apparatus having an outer wall (146) having opposed inner and outer surfaces, a central aperture (136) extending through the outer wall, and a pair of auxiliary apertures (158) disposed on the outer wall (146). Each auxiliary aperture is aligned along a respective auxiliary axis (162) and areas of the inner surface (164) of the outer wall (146) adjacent to the auxiliary apertures (158) are countersunk to define ledges (166) that are axially symmetric about the auxiliary axes (162). These assemblies obviate problems associated with rotatable molding pins and also provide the unexpected advantage of providing axial alignment of the air flow profile as air is emitted from the auxiliary apertures.
