摘要： An electromagnetic fuel injection valve wherein it is possible to prevent undesired adhesion between the respective abutting surfaces of an armature and a stationary core as well as to ensure the required wear resistance for the abutting surfaces and wherein the amount of lift of the valving element is unlikely to change is provided. After rough surfaces like satin-finished surfaces have been farmed on the abutting surfaces by shot peening, the rough surfaces are flattened by spotting. Therefore, the abutting surfaces can easily separate from each other without likelihood of adhering so closely that is difficult for them to separate from each other. Also, the amount of lift of the valving element is unlikely to change. Accordingly, the amount of fuel injected by the fuel injection valve is unlikely to change with passage of time. Thus, stable fuel supply can be performed.
摘要翻译：一种电磁燃料喷射阀，其中可以防止电枢和固定铁芯的各个邻接表面之间的不期望的粘合，并且确保抵靠表面所需的耐磨性，并且其中阀元件的升程量不太可能提供更改。在通过喷丸硬化处理在邻接表面上形成如缎面表面的粗糙表面之后，粗糙表面通过点样变平。因此，邻接表面可以容易地彼此分离，而不会很紧密地附着，难以彼此分离。此外，阀元件的升程量不太可能改变。因此，由燃料喷射阀喷射的燃料量不可能随时间而变化。因此，可以执行稳定的燃料供应。

摘要： The invention is directed to an ignition coil for an internal combustion engine which includes a columnar member having a plurality of magnetic plates, e.g., silicon steel plates stacked one on the other, each of which is a flat plate with its opposite ends having a width greater than that of its middle portion. Each silicon steel plate has a middle portion whose width is gradually increased from the plates placed at the opposite sides of the columnar member to the plate placed in the center of the columnar member, to form a circular cross section. Whereas, the opposite end portions of the columnar member have a rectangular cross section which is greater in area than the circular cross section of the middle portion, respectively. A plurality of recesses are formed on one side of each steel plate, and a plurality of protrusions are formed on the other side of each steel plate. The silicon steel plates stacked one on the other under pressure, so that the recesses and the protrusions are connected to form a plurality of stacked portions on the columnar member. The ignition coil further includes a primary winding and a secondary winding which are wound around the columnar member, a magnetic cylindrical member in which the columnar member is received, and a magnetic cylindrical case in which the cylindrical member and the columnar member are received.

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.
