    摘要: Bei einer Einspritzvorrichtung ist vorgesehen, in der Kraftstoffzuführung zur Einspritzpumpe eine unabhängig antreibbare Hochdruckpumpe einzuschalten. Hierdurch soll ermöglicht werden, die Einspritzpumpe mit einem hohen Vordruck zu beaufschlagen. Ferner ist vorgesehen, daß der Federraum des Düsenhalters der Einspritzdüse gleichzeitig durch den Vordruck beaufschlagbarwird. Es ist damit möglich, das Öffnen und Schließen der Düsennadel der Einspritzdüse bei Druckwerten zu gewährleisten, die bereits optimale Gemischbildungsverhältnisse garantieren.

    摘要: The invention relates to an injection nozzle (1) for an internal combustion engine, comprising a first needle (3) for controlling first injection holes (7) and a second needle (4) for controlling second injection holes (8). A fuel feed line (9) is connected to a fuel supply device (10) and leads to the injection holes (7, 8). A first pressure level (16) of the first needle (3) prevails during exertion of pressure in the direction of opening (19) of the first needle (4). A second pressure level (25) of the second needle (4) prevails during the exertion of pressure in the direction of opening (19) of the second needle (4). In order to reduce the response time of the second needle (4) during increased fuel high pressure, a control surface (33) is assigned to the second needle assembly (28), said control surface being arranged in a control chamber (34) that is connected to the fuel supply device and operating during the exertion of pressure in the direction of opening (19) of the second needle.

    摘要: The invention relates to a common rail injector, having an injector body (1), provided with a fuel inlet (50), communicating with a central high-pressure fuel source, outside the injector body and with a pressure chamber (17), inside said injector body, from which, depending on the pressure in the control chamber (21), high-pressure fuel is injected into a combustion chamber of an internal combustion engine, when an injector needle (8) lifts from its seat (11), whereby the pressure in the control chamber (21) is directly controlled by an actuator (58), in particular, a piezoelectric actuator. In order to reduce the installation space, another control chamber (22) is connected in series with the first control chamber (21).

    摘要: A fuel injection device for internal combustion engines includes a needle valve (3) for opening and closing an injection port (33), a control chamber (5) for applying a fuel pressure to the needle valve (3) in a needle valve opening direction, a spring (13) for applying a biasing force to the needle valve (3) in a needle valve closing direction, a piezoelectric actuator (4) for increasing and decreasing a fuel pressure in the control chamber(5), a piston (2) which slides with the needle valve (3) so as to receive the fuel pressure in the control chamber (5) at a lower end face (2b) thereof, and a pressure storage chamber (11) for storing a fuel to be supplied to the injection port (33). The fuel injection device further includes another control chamber (6) which communicates with a fuel supply line (17) for applying a fuel pressure to an upper end face (2c) of the piston (2) in a needle valve closing direction. The another control chamber (6) communicates with the pressure storage chamber (11) via communication means (22).
