    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 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.

    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: 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: A fuel injection nozzle for internal combustion engines that has a nozzle body with a valve seat disposed on the combustion chamber end and an outwardly-opening valve needle with a closing head, which has a closing cone that works together with the closing valve seat. At least one injection port is disposed in the closing head at an angle with respect to the axis of reciprocation of the valve needle, and is opened by a control edge on the nozzle body depending on the inlet pressure of the fuel. In order to minimize any deflection of the injection stream flowing out of the injection port relative to the alignment of the injection port, the port is divided into at least two parallel conduits, which are separated from each other by a dividing wall and which upon the opening stroke of the valve needle are unblocked one after the other by the control edge.
