摘要： Located between the frustoconical needle tip and the cylindrical needle shank of a nozzle needle of a fuel injection valve is a frustoconical needle portion, into which is introduced a peripheral groove. Through this kind of arrangement damping is capable of being set, depending on the position of the groove, during the axial movement of the nozzle needle.

摘要： The nozzle body (5) of a fuel injection valve has a central bore (54) in which a nozzle needle (1) is guided. The tip (52) of the nozzle body (5) has a tapered valve seat (55) which forms together with the sealing edge (27) of the nozzle needle (1) a valve (27, 55) which controls the flow of fuel to the injection holes (9) in the nozzle tip (52). Underneath the sealing edge (27) a circumferential groove (33) is disposed in the truncatoconical needle tip (30, 35, 40, 45) at the level of which the injection holes (9) are disposed, so that when the valve (27, 55) opens the nozzle needle (1) is axially stabilized and the shaping of the injected jet is improved.

The actuator has an actuator stack surrounded by a hollow cylindrical spring element and an actuator casing disposed in the spring element. The spring element is clamped, together with the actuator stack, between an actuator cap and an actuator base. An elastic compound fills gaps between the drive housing and the spring element as well as between the spring element and the actuator casing, and damps an actuator motion. A piezoelectric actuator for the servo drive and a method of producing the piezoelectric actuator are also provided.

摘要： The positioning of the actuating drive in a fuel injector with a piezoactor (2) that is screwed into the housing (1) of the fuel injector is performed by applying a voltage (U) to the piezoactor (2) that corresponds to a given idle stroke (h), and the surface grinding of the housing (3) and base plate (4) of the piezoactor (2) when voltage is applied. Between the housing (1) of the fuel injector and the housing (3) of the piezoactor (2), there is also provided a compensation collar (9) of a suitable thickness.

摘要： A nozzle needle (60) of a fuel injection valve is guided axially in a nozzle body (50), and it points with its rear end face (61) into a compression chamber (15) and is operatively connected to a damping body (40). The recesses (46, 47, 48) of the damping body (40), together with the damping bore (14), form a fuel-filled damping chamber (40). Upon valve opening, the fuel in the compression chamber is compressed, and thus the valve opening is delayed. If the nozzle needle exceeds the damping stroke (hd), then the fuel is depressurized by a communication with an outflow chamber (12). The damping body is guided over at least part of its length in the damping bore.
摘要翻译：燃料喷射阀的喷嘴针头（60）在喷嘴体（50）中被轴向引导，并且其后端面（61）指向压缩室（15）并且可操作地连接到阻尼体（40））。阻尼体（40）的凹部（46,47,48）与阻尼孔（14）一起形成燃料填充阻尼室（40）。在阀打开时，压缩室中的燃料被压缩，因此阀开启被延迟。如果喷嘴针超过阻尼冲程（hd），则通过与流出室（12）的连通而将燃料减压。阻尼体在阻尼孔中的至少一部分长度上被引导。
