Fuel injection valve for use in fuel injection system of internal combustion engine in motor vehicle, has non-magnetic intermediate part with inner bore hole whose internal diameter extends from fastening region to point of guiding region

摘要

The valve has a firm kernel (2) and a connector (16) that are connected to a non-magnetic intermediate part (120) to form an internal metallic valve tube, where the connector is arranged downstream of the kernel. The non-magnetic intermediate part has a cylindrical inner bore hole (54) whose internal diameter extends from a fastening region (55) of the intermediate part at the kernel to the point of a guiding region (56) of the intermediate part for movable armature (27). The movable armature is provided for operating a valve closing element.
