    摘要： In an injection nozzle for a fuel injection system, the opening stroke of the nozzle needle is to be limited selectively, so that different injection cross sections can be employed. To that end, the injection nozzle is provided with a nozzle body, a nozzle needle displaceable in the nozzle body, two groups of injection ports, which are uncovered as a function of an opening stroke of the nozzle needle, a piston that is connected to the nozzle needle, a stop chamber in which the piston is disposed and which is provided with an outlet, and a control valve that can open and close the outlet of the stop chamber, as a result of which the stroke of the piston in the stop chamber and thus the opening stroke of the nozzle needle can be selectively limited.

    摘要： A fuel injection system, having a fuel injection valve and a control valve, which control valve has a control valve member that is longitudinally displaceable in a control valve bore. A control valve sealing face is embodied on the control valve member; it cooperates with a control valve seat and thus controls the communication between a first pressure space and a second pressure space; the first pressure space communicates with a high-pressure collection chamber. In a valve body, a bore is embodied in which a pistonlike valve needle, with its end toward the combustion chamber, controls the opening of at least one injection opening by executing a longitudinal motion in response to the pressure in a pressure chamber; the pressure chamber communicates with the second pressure space via an inlet conduit. The first pressure space communicates via a throttle with a damping chamber, embodied as a blind bore and otherwise closed off, as a result of which pressure fluctuations that occur upon closure of the control valve are rapidly damped.

    摘要： In a fuel injection system for internal combustion engines, including an electronically triggered control valve with an axial through bore, which is divided by two valve seats into three annular chambers, to which respectively a supply line for fuel at high pressure, a high-pressure line leading away to an injection valve, and a relief line are connected, and having a control piston, which is guided in the through bore and which has two valve sealing faces cooperating with the two valve seats, respectively, the control piston according to the invention has a further valve sealing face, which cooperates with the first valve seat and whose spacing from the first valve sealing face is at least equal to the spacing between the second valve sealing face and the second valve seat when the first sealing seat is closed. A communication between the supply line and the relief line is thus reliably prevented.

    摘要： The invention relates to a 3/2-way valve for controlling the injection of fuel in a common rail injection system of an internal combustion engine, having a first switching position, in which an injection nozzle is in communication with a fuel return, and a second switching position, in which the injection nozzle is in communication with a common rail. To improve the function and quality of the injection, the 3/2-way valve includes two force-balanced control pistons, which are guided separately from one another, and on each of which a respective valve seat edge is embodied.

    摘要： A control valve and a fuel injection valve provided with same should be produced, in which it is possible to switch from a first operating state to a second operating state inexpensively and with short switching times, without requiring a hydraulic control line. To this end, a control valve is provided, which has a valve housing, a pressure chamber filled with electrorheological fluid, a displacing element that can slide in the valve housing and protrudes into the pressure chamber, and two electrodes that can apply an electrical field to the electrorheological fluid.

    摘要： In a fuel injection nozzle having a nozzle body which body has one first and one second group of injection ports, one first and one second nozzle needle, and one separate pressure chamber for each nozzle needle, so that the injection needles are adjustable independently of one another between a closed position, in which the injection ports associated with the corresponding nozzle needle are closed, and an injection position, in which the corresponding injection ports are opened, a free choice of injection cross sections is to be made possible, while the design is simple. To that end, it is provided that the two nozzle needles adjoin one another.
