Electronic control diesel engine fuel injector with control valve

The invention relates to an electronic control diesel engine fuel injector with a control valve. The electronic control diesel engine fuel injector with the control valve comprises a fuel injector body and the control valve which is arranged in an inner cavity of the fuel injector body. The electronic control diesel engine fuel injector with the control valve is characterized in that the control valve comprises an armature, a control valve base, a sealing matching member and a throttle sealing board. The throttle sealing board is placed on an installation end face of the inner cavity of the fuel injector body. The control valve base is placed on the throttle sealing board and is installed with the fuel injector body in a connected mode. The control valve base generates downward press force through installing torque to be pressed on the upper end face of the throttle sealing board, so that the lower end face of the throttle sealing board is tightly pressed on the installation end face of the inner cavity of the fuel injector body. The control valve is ingenious in structure, electronic control diesel engine fuel injector with the control valve applied is applicable to occasions with high pressure, pretightening force of a return spring of the armature of the common-rail fuel injector is greatly reduced, even though only small spring pretightening force is used, a pressure control cavity can be completely sealed, and highest pressure of a common-rail system can be improved to above 200 MPa.
