Method and device for producing a perforated disc for an injector valve perforated disc for an injector valve and injector valve

摘要

Method according to the invention for producing a perforated disc, first prepare a sheet metal foil 35, and forming the after sheet metal foil (35) forming the opening 27 and the auxiliary openings (49, 50) on, and the center to a large number of perforated discs band (39) having a circular portion 53 exists overlap each sheet metal foil (35), and using the bonding process connected to the sheet metal foil (35) and thereby to match, then the circular portion it is characterized by 53 or perforated disc 21, with the step of separating the individual screen.; The thus prepared perforated disc is particularly suitable for use in a fuel injection valve used in a mixed concentrated external ignition internal combustion engine.
