Beschreibung
Zusammenfassung:	The method for producing and securing an apertured disk for a fuel injector is distinguished by the use of the following method steps: a) making available a flat, metallic sheet having a constant thickness, b) reducing the thickness in one region of the sheet by impressing or embossing, c) introducing at least one spray-discharge opening in the region having reduced thickness, d) machining the sheet until an apertured disk having predefined outside dimensions is attained, and e) securing the apertured disk on a valve-seat member of the fuel injector in such a way that a lower end face of the valve-seat member overlaps an intake region of the apertured disk produced by the thickness reduction, such that the at least one spray-discharge opening is covered.
