Abstract
In an electromagnetic fuel injection valve, a valve body guide hole () which is connected to a valve seat () of a valve seat member () and slidably guides a valve body (), and a large-diameter hole () which is connected to a rear end of the valve body guide hole () via a tapered hole () and has a diameter larger than that of the valve body guide hole (), are provided in the valve seat member () of a valve housing (), whereas a first longitudinal hole () which communicates with a fuel intake cylinder () is provided in a fixed core (); a second longitudinal hole () which communicates with the first longitudinal hole () is provided from a movable core () to a valve shaft (); a traverse hole () which opens the second longitudinal hole () to the large-diameter hole () is provided in the valve shaft (); and a relationship between the diameter (D) of the large-diameter hole () and the diameter (D) of the valve body guide hole () satisfies D/D<0.6. Thus, it is possible to provide an electromagnetic fuel injection valve which atomizes the injected fuel in a good condition and is compact in size.
