Electromagnetic fuel injection valve |
摘要 |
An electromagnetic fuel injection valve wherein a central pipe part has satisfactory mechanical strength and an intermediate portion of the pipe part is surely made non-magnetic is provided. The electromagnetic fuel injection valve has a core surrounded by a solenoid coil. A valve housing is disposed forward of the core. The core and the valve housing are connected through a thin-walled portion. The wall thickness of the thin-walled portion is smaller than the wall thickness of the core and that of the valve housing. The core and the thin-walled portion, together with the valve housing, are formed in an integral structure. The thin-walled portion has a sufficient wall thickness to provide satisfactory mechanical strength. The thin-walled portion is modified into a high-hardness non-magnetic portion by a carbulizing treatment.
