    摘要： A first valve element (32) and second valve element (34) are arranged in a pressure switching chamber (30) of a three-way valve (8). When switching a destination of a fuel flow passage (15) from a high pressure fuel feed passage (5a) to a low pressure fuel return passage (26a), the state where the first valve element (32) is open and the second valve element (34) is closed is switched through a state where the first valve element (32) and second valve element (34) are both closed to a state where the first valve element (32) is closed and the second valve element (34) is open. Fuel pressure of a pressure control port (55) sealed by a sliding seal face (53) formed at an outer circumference of the second valve element (34) is used to control an opening timing of a needle valve (9).

    摘要： The invention relates to a system for injecting fuel into a combustion chamber of an internal combustion engine, having a fuel injector, which can be subjected to fuel at high pressure and which is actuatable via a metering valve, by which the pressure in an injection valve member control chamber or in a control line is controllable such that an injection valve member opens and closes for injecting fuel. The injection valve member control chamber can be evacuated via an outlet throttle device into a control line which has a smaller throttle cross section than an inlet throttle device, by way of which the injection valve member control chamber can be filled.

    摘要： The invention relates to a common rail fuel injector having an injector housing with a fuel inlet in communication with a central high-pressure fuel reservoir outside the injector housing and with a pressure chamber inside the injector housing. A control valve assures that a nozzle needle lifts from a seat when the pressure in the pressure chamber is greater than the pressure in a control chamber that communicates with the fuel inlet via an inlet throttle. The control chamber is defined by a bush that is displaceable, causing a sealing action, on the end of the nozzle needle remote from the combustion chamber and that is kept in contact against the injector housing with the aid of the nozzle spring.

    摘要： A fuel injector (100) for an internal combustion engine is disclosed. The fuel injector is particularly suitable for use as a dual fuel injector, and comprises a generally tubular outer valve needle (130), an inner valve needle (140) slidably received in the outer valve needle (130), and a nozzle body assembly (112) comprising a tip part (120) and a needle guide part (118). The tip part (120) defines a seating region (120f) for the outer valve needle (130), and the needle guide part (118) comprises a guide bore (118e) for slidably receiving the outer valve needle (130). In one embodiment, the tip part (120) and the needle guide part (118) are made from different materials, and a biasing spring (148) for the outer valve needle (130) is housed in the nozzle body assembly (112).
