Abstract (en)
[origin: US6186472B1] A fuel injection valve has a metal base body extending over its entire axial length, which includes a core/internal pole and a valve jacket. The internal pole is produced by extrusion and includes a valve inlet connection, the actual core of the electromagnetic circuit, a magnetic choke point and an area for guiding an armature. However, the valve jacket is produced by deep drawing. In addition to its function as a housing part, the valve jacket also serves as a valve seat carrier. A clearance is formed between the valve jacket and the internal pole, holding a magnet coil which is sealed by a ring gasket and is therefore dry.This fuel injection valve is suitable in particular for use in fuel injection systems of internal combustion engines with spark ignition and gas mixture compression.
