摘要： A fuel injector with an injector body is disclosed which has at least two separate function units that are largely independent of one another. The function units are reversibly joined to one another by a connecting element and at least one positioning pin. The two function units can be produced and tested separately, which greatly simplifies both the production process and maintenance of the fuel injectors and lessens the vulnerability of the fuel injectors to malfunction.

摘要： An injector with an adjustable-metering servo valve is provided. The injector has a shutter actuated by an armature of an electromagnet. The armature is mobile for an opening stroke defined by a surface of the core of the electromagnet, which is fixed in the casing by a ring nut and a hollow support of the core. The hollow support has a first contact surface that acts on a flange of the core. Set between the surface and a shoulder of the casing is a shim. An annular projection, having a second contact surface, is set between the surface and a shoulder of the casing. The second contact surface is contained at least in part in the area corresponding to the first contact surface so that the stroke of the armature is adjusted by plastic deformation of the shim or of the surface of the core.

摘要： The invention relates to a fuel injector having a solenoid valve for actuating an armature assembly which is configured in one piece or a plurality of pieces. A closing element is actuated via this in order to relieve the pressure in a control chamber. The armature assembly is guided in an armature guide which is fastened in the injector body by means of a valve-clamping screw. In a fixing region in the injector body, the armature guide has at least one circumferential recess which allows for deformation of the fixing region during fastening by the valve-clamping screw.

摘要： With reference to FIG. 1, the present invention provides an internal combustion engine (10) comprisinga variable volume combustion chamber (13); an air intake system (18,20,21) for delivering charge air to the combustion chamber (13); an exhaust system (17) for relaying combusted gas from the combustion chamber (13) to atmosphere; and a fuel injection system (19, 21, 22, 23, 24, 25, 26) for delivering fuel into the charge air for combustion therewith in the combustion chamber (13). The fuel injection system (19,21,22,23,24,25,26) comprises a fuel injector (19) which functions as a positive displacement pump and dispenses an amount of fuel which is fixed for each and every operation of the injector (19); and a controller (23) which controls the operation of the fuel injector (19). In response to an increasing engine speed and/or load the controller (23) increases in amount the fuel delivered per engine cycle by increasing in number the occasions the fuel injector (19) is operated per engine cycle. In response to a decreasing engine speed and/or load the controller (23) reduces in amount the fuel delivered per engine cycle by reducing in number the occasions the fuel injector (19) is operated per engine cycle.

摘要： An injector has the solenoid valve including a solenoid coil, a stator, a stopper, a housing, a terminal, and a bush. The stator has the solenoid coil therein, and attracts an armature to one side in an axial direction of the armature upon energization of the solenoid coil. The stator is on the one side of the armature. The stopper restricts an amount of displacement of the armature toward the stator. The housing is on the one side of the stator. The terminal is inserted in the housing, and electrically connected to the solenoid coil. The bush is received by the housing, and insulates the terminal from the housing. The bush is forcibly inserted into an attachment hole, which is formed in the housing.

摘要： An injection unit has an injector arrangement connected to a pressure reservoir by a pressure line arrangement The injector arrangement has at least one servo injection valve and a control valve for the release of fuel from a control chamber into a fuel return line leading to the fuel tank The Valve may be operated by a piezoelectric actuator to cause a displacement of a nozzle body in the direction of an injection passage opening for initiating an injection process by pressure reduction in the control chamber. The fuel return line has a controllable valve, which restricts the fuel flow in the fuel return line in the actuated state. It is, thus, possible to reduce the effects of a change of length of the piezoelectric actuator, which exceeds the so-called tolerance gap in the servo injection valve, which are detrimental to the operation of the injection unit.
摘要翻译：注射单元具有通过压力线布置连接到压力储存器的喷射器装置。喷射器装置具有至少一个伺服喷射阀和用于将燃料从控制室释放到通向燃料箱的燃料返回管线的控制阀阀可以由压电致动器操作以使喷嘴体在喷射通道开口的方向上移位，以通过控制室中的压力降低来启动喷射过程。燃料返回管线具有可控制的阀，其限制在致动状态下燃料返回管线中的燃料流量。因此，可以减少超过伺服喷射阀中所谓的公差间隙的压电致动器的长度变化的影响，这对喷射单元的操作是有害的。

摘要： A fuel injector with a pressure booster supplied with fuel at high pressure. A work chamber of the pressure booster is separated from a differential pressure chamber via a booster piston. The pressure relief and the subjection to pressure of the differential pressure chamber are effected via a switching valve which communicates with the differential pressure chamber via a control line. A pressure chamber on an injection valve member communicates with a compression chamber of the pressure booster via a pressure chamber supply line. The switching valve is embodied as a direct-switching 3/2-way valve, whose valve needle is pressure-balanced and has both a sliding seat and a slide seal.
