    摘要： A piston fuel pump for an internal combustion engine comprises a pump housing (26), a piston and a non-return discharge valve (38) having a valve element (44) and a guide element (50) for guiding the movement of the valve element (44). According to the invention, the guide element (50) is at least indirectly pressed in a radial manner into an opening (41) in the pump housing (26).

    摘要： The invention relates to a method for operating a fuel system (10) for an internal combustion engine, wherein a metering device (22) for measuring a delivery quantity of the fuel can be opened and/or closed by means of an electrical actuation device (20), and wherein a valve element (54) of the metering device (22) can switch to a first position (45) when the actuation device (20) is not activated and to a second position (47) when the actuation device (20) is activated. The first position (45) corresponds to a closed metering device (22) and the second position (47) corresponds to an open metering device (22). The method is characterised by the following steps: (a) activation of the electrical actuation device (20) in at least one first cycle in such a manner that the valve element (54) switches reliably to the second position (47); (b) activation of the electrical actuation device (20) in at least one second cycle in such a manner that the electrical actuation device (20) is activated from activation to activation with activation energy which reduced step by step until a limit reduction is reached, at which the valve element (54) is only just or no longer switched to the second position (47); (c) determination of a first activation energy which corresponds to the limit reduction; (d) subsequent activation of the actuation device (20) taking the first activation energy into account.

    摘要： The invention relates to an arrangement (1) which is used in particular as a fuel injection system for high-pressure fuel injection in internal combustion engines, comprising a fuel distributer (2) and multiple fuel injection valves (3, 4). Each of the fuel injection valves (3, 4) is arranged on a cup (9, 10) of the fuel distributer (2). At least one of the fuel injection valves (3, 4) is secured to the corresponding cup (9) by means of at least one retaining element (30). A bearing surface (19) is provided on the outer face (18) of the cup (9). A supporting surface (17) is provided on the lower face (16) of the cup (9). Furthermore, the retaining element (30) is designed as a retaining bracket (30). A bearing surface (21) is provided on an outer face (20) of the fuel injection valve (3). The retaining bracket (30) engages behind the bearing surface (19) of the cup (9) and behind the bearing surface (21) of the fuel injection valve (3). Furthermore, the retaining bracket (30) urges the fuel injection valve (3) against the supporting surface (17). Composite damping elements (11, 13) are arranged between the fuel injection valve (3) and the supporting surface (17) of the cup (9) and between the bearing surface (21) of the fuel injection valve (3) and the retaining bracket (30). It is thus possible to decouple the fuel injection valves (3, 4) from the fuel distributer (2), whereby noise emissions are reduced.

    摘要翻译： 本发明涉及一种装置（1），其特别是用作内燃机中用于高压燃料喷射的燃料喷射系统，其包括燃料分配器（2）和多个燃料喷射阀（3,4）。 每个燃料喷射阀（3,4）都布置在燃料分配器（2）的杯子（9,10）上。 至少一个燃料喷射阀（3,4）通过至少一个保持元件（30）固定到相应的杯（9）上。 支承表面（19）设置在杯子（9）的外表面（18）上。 支撑表面（17）设置在杯子（9）的下表面（16）上。 此外，保持元件（30）被设计为保持支架（30）。 在燃料喷射阀（3）的外表面（20）上设有支承面（21）。 保持支架30接合在杯9的支承表面19之后和燃料喷射阀3的支承表面21之后。 此外，保持支架（30）将燃料喷射阀（3）推靠在支撑表面（17）上。 在燃料喷射阀（3）和杯状件（9）的支承表面（17）之间以及在燃料喷射阀（3）的支承表面（21）与保持器（3）之间布置复合阻尼元件（11,13） 支架（30）。 因此可以将燃料喷射阀（3,4）与燃料分配器（2）分离，从而降低噪音。
