    • 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.
    • 用于制造和固定用于燃料喷射器的孔径盘的方法的区别在于使用以下方法步骤:a)提供具有恒定厚度的平坦的金属片,b)通过以下方式减小片材的一个区域中的厚度 c)在具有减小厚度的区域中引入至少一个喷射排出口,d)加工该片材,直到获得具有预定外部尺寸的孔径盘,以及e)将开孔盘固定在阀座构件上 以使得阀座构件的下端面与通过厚度减小产生的开孔盘的进气区域重叠,使得至少一个喷射排出口被覆盖。
