摘要： An injector having a tube attached to an armature. The injector includes a solenoid portion and a valve portion controlled by the solenoid portion. The armature includes a small diameter portion. Also included is a tube having a cavity, a first end of the tube is connected to the small diameter portion, and a ball is connected to a second end of the tube, such that the ball is selectively in contact with a valve seat. A hermetic weld connects the ball to the second end, and at least one heat affected zone is located in proximity to the hermetic weld. A coating substantially surrounds the heat affected zone and at least a portion of the ball, such that the coating prevents the heat affected zone from being exposed to diesel exhaust fluid and thus subsequent corrosion.

摘要： In regard to a junction between a metal joint and an electromagnetic fuel injection valve, a screw structure or the like is used to secure the higher sealing property and strength than those of the conventional valve, and thus, the valve becomes larger in general than the conventional valve using an O-ring structure. In addition, there is an example in which resistance welding is used in order to provide a smaller size than the screw structure as another embodiment. In this case, it is necessary to increase a dimensional accuracy of a plane on which the resistance welding is performed in order to reduce a positional deviation or squareness between the metal joint and the electromagnetic fuel injection valve. In addition, welding distortion is caused by contraction generated after the welding if the amount of weld penetration through the welding is significantly increased in order to secure the high strength, which leads an increase in the amount of the positional deviation or an increase in the squareness even when the dimensional accuracy of the plane on which welding resistance is performed is increased. In the present invention, a core as one of components that configure an electromagnetic fuel injection valve is joined with a metal joint by welding to have each melting amount of welded portion of the metal joint and the core being set such that a metal joint side has a larger melting amount than a core side. Further, a metal joint end surface, a fuel seal portion having a smaller cross-sectional area than an area of the metal joint end surface, and a core end surface having a larger area than the cross-sectional area of the fuel seal portion are provided such that the metal joint end surface and the core end surface communicate via the fuel seal portion.
摘要翻译：关于金属接头和电磁燃料喷射阀之间的连接点，使用螺杆结构等来确保比常规阀更高的密封性能和强度，因此，阀通常比常规阀使用O形圈结构。此外，作为另一实施例，存在使用电阻焊接以提供比螺杆结构更小的尺寸的示例。在这种情况下，为了减小金属接头和电磁燃料喷射阀之间的位置偏差或矩形度，需要增加进行电阻焊接的平面的尺寸精度。此外，为了确保高强度，如果通过焊接的焊接渗透量显着增加，则焊接后产生的收缩导致焊接变形，这导致位置偏差量的增加或矩形度的增加即使进行焊接电阻的平面的尺寸精度增加。在本发明中，作为构成电磁燃料喷射阀的部件之一的铁心通过焊接与金属接头接合，使金属接头和铁芯的焊接部分的熔融量设定为金属接合面为比芯侧更大的熔化量。此外，金属接合端面，具有比金属接头端面的面积小的横截面积的燃料密封部以及具有比燃料密封部的横截面积大的面积的芯端面，设置成使得金属接合端面和芯端表面经由燃料密封部连通。

摘要： A fuel injection valve according to the present invention has an expanded portion formed in a first injection-hole plate on an upstream side, thereby allowing positional misalignment between injection-hole portions. As a result, a radial dimension between an inner diameter-side circumferential edge of an upstream-side injection hole outlet portion and an inner diameter-side circumferential edge of a downstream-side injection hole inlet portion is not required. Thus, a plate thickness of a second injection-hole plate on a downstream side can be kept to minimum. As a result, weldability between an injection-hole plate body and a valve seat is improved.
