Abstract (en)
[origin: WO2005010349A1] The invention relates to a fuel injection valve comprising an injection duct (11) via which fuel can be injected into the combustion chamber. The injection duct (11) has an inlet opening (30) and an outlet opening (38), and a cylindrical section (32) is formed at its end located on the side of inflow with regard to the direction of flow of the fuel. A conical section (34) is connected to the cylindrical section (32), narrows in the direction of flow and extends up to the outlet opening (38) of the injection duct (11). According to a method for producing injection ducts (11) of this type, a laser beam (54) is directed from the outside through the injection duct (11) and onto a mirror (50) whereby enabling the formation of the widening of the cylindrical section.
