摘要： The invention relates to a device for axially connecting an external pipe section to a coaxial peg or internal pipe section that engages in the external pipe section, in particular for connecting the drain connecting piece of an injector for injecting fuel into internal combustion engines to a fuel return connector. The external pipe section has two diametrically opposed retaining slots that penetrate the wall of the external pipe section and which correspond to grooves on the periphery of the peg or internal pipe section. Two opposing sprung retaining arms of a clamp-type retaining clip pass through the retaining slots of the external pipe section from the exterior and snap into the grooves of the peg or internal pipe section in a sprung manner. One essential feature of the invention is that the parallel retaining slots of the external pipe section are offset in height in relation to one another, while the whole of the retaining clip, when not fitted onto the pipe sections, lies on one plane.

摘要： 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. The actuator booster piston has a second pressure surface, which, as an additional control surface, is associated with the control chamber.

摘要： The invention relates to a valve for a fuel injection system, having a valve seat embodied in a valve housing, and having a valve member which is movable in the valve housing and has a sealing face that when the valve is closed rests sealingly against the valve seat and when the valve is open, together with the valve seat, defines a valve gap through which fuel flows. To prevent cavitation damage, the valve member has an encompassing hollow throat, which is disposed in the flow direction immediately downstream of the sealing face and is adjoined by an encompassing cross-sectional thickening of the valve member.

摘要： The invention relates to a fuel injector for injecting fuel into the combustion chamber of an internal combustion engine, comprising a nozzle needle (1) which is able to perform stroke motions and by the stroke motion of which at least one injection opening can be exposed or closed, and further comprising a control valve (2) for controlling the stroke motion of the nozzle needle (1) in that, depending on the respective switch position of the control valve (2), hydraulic pressure applied in closing direction to the nozzle needle (1) in a control chamber (3) is altered, and further comprising a sensor array (4) for detecting the needle closing time. According to the invention, the sensor array (4) is arranged in the low-pressure area of the fuel injector in a space (5) which is sealed with respect to the fuel-conducting area (6). Sealing of the space (5) is effected by a membrane (7) made of a fuel-resistant, electrically conductive material, allowing the membrane (7) to also be utilized for implementing a ground connection.

摘要： A method for operating a fuel injection system of an internal combustion engine is described. The fuel injection system has an injector for metering fuel into a combustion chamber of the internal combustion engine. The injector has an actuator, a control valve and a nozzle needle. In the method, the actuator is supplied a voltage and/or a current during an activation period. The control valve is set into a lifting motion by the actuator. The injector is opened and closed by the nozzle needle, using the lifting motion of the control valve. A further time period is ascertained. The further time period ends at the closing time of the nozzle needle. A function is ascertained, which links the activation period to the further time period. A shortest activation period, for which the nozzle needle opens and produces an injection, is ascertained with the aid of the function. An opening delay period (do1) of the nozzle needle is ascertained as a function of the shortest time period.

摘要： The invention relates to a control chamber (7), the pressure of which determines the strokes or positions of a nozzle needle (6), and which is assigned to a force or pressure sensor (20) in order to detect the progression of the control chamber pressure. Because the control chamber pressure significantly changes during the closing of the nozzle needle (6), the operating phases of the injector can be exactly determined from the sensor data and supplied to an engine controller.
