Abstract

A spray nozzle orifice member which produces a flat fan-shaped spray making it ideally suited for the application of coatings. The orifice is formed by the intersection of a straight bottomed slot on one side and a curved bottom V-shaped groove on the opposite side of said member. The improvement resides in the ease and economy of fabrication of such a spray nozzle member as a function of the groove-slot combination concept.

Claims

1. A spray nozzle orifice member, adaptable to be joined with a nozzle body and which produces a flat fan-shaped spray, said nozzle orifice member having an inner and outer face, said outer face containing therein a V-shaped groove having oppositely curved walls and a concavely curved bottom, said inner face containing therein a slot having essentially straight walls and a straight bottom, said groove and said slot being oriented at approximately right angles to each other and intersecting so as to form an elliptical orifice.

2. The spray nozzle orifice member of claim l wherein said straight bottom of Said slot has a radius of curvature which meets said essentially straight walls of said slot.

3. The spray nozzle orifice member of claim l wherein said straight bottom of said slot meets said essentially straight sidewalls at an angle of approximately 90* .

4. The spray nozzle orifice member of claim l wherein said orifice member is disc shaped and fabricated of a material selected from the group consisting of tungsten carbide, boron carbide, aluminum oxide, bauxite, steel, iron, bronze, copper, zinc, phenol-aldehyde polymer, epoxy resin, unsaturated polyester resin, polytetrafluoroethylene, polyethylene, and polypropylene.
