  • Publication number: 20080093481
    Abstract: An injector having an injector body to which a fuel line is connected for delivering fuel at high pressure. A filter bore is formed in the body and a fuel filter is disposed, through which filter the delivered fuel flows. A sealing seat is formed in the filter bore against which seat the end of the fuel line is pressed upon fastening of the fuel line to the injector body. The filter bore discharges at the outside of the injector body. The sealing seat is disposed with its longitudinal axis inclined to the longitudinal axis of the filter bore, and in the injector body, a bore extending at least approximately coaxially to the sealing seat is provided, into which the end region of the fuel line plunges. By the end region, plunging into the bore, of the fuel line, an outer end region of the filter bore, discharging at the outside of the injector body, is separated from an inner end region, subjected to high pressure, of the filter bore, and the fuel filter is disposed in the inner end region of the filter bore.

  • Patent number: 7258283
    Abstract: A fuel injector with a direct needle control for an internal combustion engine, having an actuator, a hydraulic booster, and a nozzle needle guided in a nozzle body and acting on a nozzle needle sealing seat. The hydraulic booster includes a booster piston connected to the actuator and a nozzle needle booster piston connected to the nozzle needle; a booster chamber in the form of an actuator coupler chamber is associated with a pressure surface of the actuator booster piston; and depending on the pressure in the actuator coupler chamber, the nozzle needle is lifted away from the nozzle needle sealing seat, thus initiating an injection. In addition to the actuator booster piston, a control element is provided that is able to execute a stroke motion, is hydraulically coupled to the actuator coupler chamber by means of a first control surface, and is associated with a control chamber by means of a second control surface.

  • Patent number: 6764061
    Abstract: A solenoid valve is for controlling an injection valve of an internal combustion engine, including a housing part, an electromagnet having a magnetic coil and a magnetic core, an armature acted upon by a valve spring and axially movable between the electromagnet and a valve seat, and a control valve member moved by the armature and cooperating with the valve seat for opening and closing a fuel passage, in which the armature is situated in the housing part movable in the radial direction free from mechanical guiding means. A further development provides that, when a current is applied to the electromagnet,the armature may be aligned in the radial direction, by magnetic reluctance forces then acting upon the armature, into a centrical position with reference to the centerline of the electromagnet.

  • Patent number: 6520143
    Abstract: A preinjection valve with a valve body, in which an inlet conduit is embodied which can be filled with fuel at high pressure via a high-pressure pump. An outlet conduit is embodied in the valve body and discharges laterally into the inlet conduit and communicates with a fuel injection valve via a high-pressure line. A preinjection valve member is guided sealingly in the inlet conduit and is moved counter to a closing force by the fuel pressure in the inlet conduit and after executing a preinjection stroke (hv) comes to rest on a deflection valve member guided, likewise sealingly, in the inlet conduit. By the motion of the preinjection valve member, a preinjection quantity is pumped into the outlet conduit and delivered to the fuel injection valve.
