Nozzle assembly for electrostatic spray guns

An air atomizing nozzle assembly for electrostatic spray guns is disclosed. The nozzle assembly includes an air cap having a central bore which surrounds a fluid tip nozzle. The bore has a plurality of axially aligned holes evenly spaced about its circumference and intersecting the edge thereof thereby defining a plurality of uniformly dimensioned, circumferentially spaced axial gas flow passages with spaced, radially extending ribs therebetween. The ribs between the holes engage the outside diameter of the nozzle to align its center axis on the axis of the central bore. The air cap and nozzle tip thus cooperate to form a plurality of uniform gas flow passages around the nozzle thereby producing a uniform atomizing air flow pattern around the nozzle. The air cap is retained in a one-piece resilient retaining ring by snapping the air cap into position over an annular lip of the ring. The air cap and retaining ring form a seal which prevents control air from escaping to the atmosphere.
