SPRAY NOZZLE ORIFICE MEMBER
First Claim
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.

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.
