    Abstract: The present invention relates to a control valve for a fuel injector. The control valve has a control valve body which defines a supply passage for high pressure fuel. A control chamber and a pressure compensating chamber are provided in the control valve. The control chamber and the pressure compensating chamber are both in fluid communication with the supply passage. A control valve member is provided for controlling fuel pressure in the control chamber. The pressure compensating chamber is spaced radially outwardly from the control chamber. The invention also relates to a control valve member having a pressure compensating cavity.

    Abstract: A fuel injector includes fixed metal components, in particular an injector body, a solenoid actuator equipped with a retaining spring that holds a control valve stem, a control valve body including a seat for the control valve stem, a spacer between the body of the control valve and an injection nozzle, a control chamber, and an injection needle seat. The fuel injector also includes movable metal components, in particular the control valve stem and an armature thereof and an injection needle. Surfaces of the metal components that are in contact with one another are contact surfaces. Resistive surface coatings are arranged on a number of the contact surfaces. The overall electrical resistivity of the injector between the body of the solenoid actuator and the body of the injector varies by at least three distinct ohm values intermittently according to the kinetics of the injection needle of the injector.

    Abstract: A control valve for controlling the movement of a needle of a fuel injector includes a coil which is attached to a housing of the injector, which housing engages with an armature which can be moved between an open position and a closed position. The armature includes a magnetic plate, through the center of which a rod, which forms a valve piston, extends perpendicularly to the plate to a remote end. The piston slides into a bore in the injector housing, the movements of the armature and of the piston opening or closing channels in which pressurized fuel flows. The armature is provided with a device for quickly discharging the fuel which is captive between the coil and the plate.
