ABSTRACT:
A dual stream thin edge orifice disk is defined as a disk having a pair of orifices positioned to direct the flow of fluid from the interior portion of a valve into two different streams. The dual streams may be parallel or typically diverge at an angle for directing the stream to two adjacent engine valves in the situation wherein the valve is an electromagnetic fuel injector for an internal combustion engine. To have the dual stream flow in a direction that is not parallel, the area of the disk surrounding the dual orifices is embossed and the orifices are positioned along the sides of the embossment between the base and the apex thereof. The manufacturing of the accurately sized orifices in the disk is accomplished by means of a progressive die. One of the stations of the die provides a coining operation on the orifice. Such coining operation is adjustable by means of a micrometer adjustment. Another of the stations provides a forming operation wherein an embossment is formed in such a manner that the orifices are positioned on the sides of the embossment between the base and the apex. In another embodiment of a valve, a pair of dual orifice disks are position adjacent each other with the orifices of the first disk overlapping the orifices of the second disk.
