Abstract
A perforated plate that provides an improvement in a fuel injection valve that is used to inject fuel into the intake tube of a mixture-compressing internal combustion engine having externally supplied ignition. The perforated plate is secured on a nozzle body of a fuel injection valve, in which a tight-seat face is embodied. Cooperating with the tight-seat face is a valve needle, to which an armature is secured, which is actuated electromagnetically by a magnetic coil. The perforated plate is secured downstream of the tight-seat face, and is provided with opposite disposed elongated indentations each of which slope toward and discharge into a cylindrical hole in order to form fanlike streams that are ejected through the cylindrical hole.
