FUEL INJECTION VALVE
A fuel injection valve includes a valve body, a fixed core, a movable core, a spring and a cup. The movable core has a first core contact surface which contacts the valve body when the movable core is moved by a predetermined distance away from a nozzle hole, and a second core contact surface which...

| description | A fuel injection valve includes a valve body, a fixed core, a movable core, a spring and a cup. The movable core has a first core contact surface which contacts the valve body when the movable core is moved by a predetermined distance away from a nozzle hole, and a second core contact surface which contacts the cup when the movable core is moved away from the nozzle hole. The movable core, the cup and the valve body form a fuel storage chamber which is surrounded by the movable core, the cup and the valve body to accumulate fuel. The first core contact surface is located inside the fuel storage chamber. The first core contact surface and the second core contact surface have a communication groove through which the inside and the outside of the fuel storage chamber communicate with each other. |
