Abstract
An electromagnetic fuel injection valve comprises a valve body, a valve seat which cooperates with the valve body, a fuel injection port disposed downstream of the valve seat, and a dividing device which serves to divide injection fuel injected from the fuel injection port. The dividing device is formed integrally with a member in which the fuel injection port is formed and includes parallel walls substantially parallel to each other with the fuel injection port interposed therebetween and arcuate walls connected to the parallel walls having a diameter larger than that of the fuel injection port. The walls extend from said member in a direction of an axis of the valve. The dividing device has an outer diameter substantially equal to the largest diameter of the valve seat.
