    摘要： The invention relates to a fuel injection arrangement for internal combustion engines, said arrangement comprising an accumulator for storing fuel under pressure, and at least one stroke-controlled injector which is connected to the accumulator by means of a high-pressure line for the fuel, the accumulator and the high-pressure line being part of a high-pressure system. The inventive arrangement is characterised in that a device is provided for removing fuel from the high-pressure system and for deriving fuel in a low-pressure region when the injection valve is closed, so that when fuel is removed, a vibration of the fuel is generated in the high-pressure line (14) associated with the injector (1). This enables the injection to begin only when vibration generated in the hydraulic system, between the accumulator and the injector, creates pressure on the injector which is higher than the pressure dissipated when the valve is opened.

    摘要： The invention relates to a fuel injection device for injecting fuel into a combustion chamber (18) of an internal combustion engine, having a control valve (36) comprising a valve piece (4) in which a valve body (37) is guided such that it can be moved back and forth to represent a valve seat (39). In order to minimize leakage during operation of a fuel injection device, the valve body (37) has a first contact surface (71) on one end which is arranged when the valve seat (39) is closed in a plane with a second contact surface (72) designed on the valve piece (4) such that the two contact surfaces (71, 72) contact a common opposite surface (73) in a sealing manner.

    摘要： The invention relates to a fuel injection device (10), especially an injector, for internal combustion engines. Said device comprises a base (12), an injection housing (14) and a tensioning device (48). Said tensioning device (48) includes at least one adjusting nut (16) with an annular link (32) and an annular collar (40) on the injection housing (14). The tensioning device (48) axially braces the injection housing (14) with the base (12). The injection device further comprises a fuel inlet (24) and at least one valve element (22). In order to improve sealing between the base (12) and the injection housing (14), the tensioning device (48) is provided with at least one annular surface facing the annular link (32) of the adjusting screw (16) and being convex in the manner of a spherical segment surface (41).

    摘要： The invention relates to a fuel injector (10), having an electrical actuator (28), particularly an electromagnet, for injecting fuel into the combustion chamber of an internal combustion engine. A closing element (44), which releases or closes an outlet (62) of a control chamber (60) can be operated by the actuator (28). An armature (20) operating the closing element (44) has openings (58, 94, 104) which are opened when the closing element (44) is closing and closed when the closing element (44) is opening.
