噴射器。A valve housing having a fuel injection port and a valve seat at the tip and a fuel passage passing through the shaft center, and a valve housing that is slidably inserted into the fuel passage and normally closes the fuel injection port by a compression spring. An on-off valve, an armature connected to the rear end of the on-off valve, a fixed magnetic core that faces the rear end surface of the armature through a certain gap and has a fuel passage penetrating through the shaft center, and a stationary magnetic core that surrounds the fixed magnetic core. An electromagnetic fuel consisting of an attached W coil and a magnetic housing that couples the PULBURY 1 housing and the fixed magnetic core, and which opens the opening/closing valve and injects pressurized fuel while receiving a valve opening time signal to the electromagnetic coil. 1. An electromagnetic fuel injector, characterized in that a cone is attached to the center of the opening of the fuel injection port with the apex positioned in a direction in which it collides with the injected fuel.
