Multi orifice structure and method of making same

Abstract(summary):

The invention is a multiorifice structure and method of manufacture. The structure comprises a plurality of triangularly shaped orifices angularly disposed with respect to a common axis. The structure is formed by fusing together concentric alternating layers of cylindrical members and parallel rods angularly disposed with respect to the axis of the cylindrical members. The fused structure is sliced generally normal to its axis to produce a plurality of multiorifice wafers or discs. The interstices between the rods and the cylindrical members form a plurality of small triangularly shaped orifices particularly well suited to use as an atomizer for an internal combustion engine fuel injector valve.
