ABSTRACT:
A method for producing a nozzle holder for an injection valve, having a valve closing member comprising an armature and a valve closing body, disposed within a nozzle holder. The nozzle holder has a bore which is provided with at least one guide protrusion on end and that extends at least partway around the bore. The guide protrusion is stamped into a guide segment of the nozzle holder. The injection valve is especially suited for fuel injection systems of mixture-compressing internal combustion engines with externally supplied ignition.
