    • A fuel injection pump for internal combustion engines is proposed in which cavitation is avoided at the sealing surface between a threaded connection element which contains the pressure valve and a securing flange of the pressure valve housing which protrudes radially outwardly therefrom. The securing flange is attached to a cylindrical portion on the end of the valve housing remote from the pressure line leading to the injection nozzle and a sealing member is fitted into an intermediate chamber between the cylindrical portion and an inner wall of the threaded connection element. This sealing member is pressed with at least one annular contact surface onto the cylindrical housing portion and with a different contact surface, axially displaced with respect to the first, is pressed against the threaded connection element. The sealing member may be embodied as a thin-walled sheet-metal sleeve, may comprise a spiral spring, or may be made of plastic.
    • 提出了一种用于内燃机的燃料喷射泵,其中在包含压力阀的螺纹连接元件和压力阀壳体的从其径向向外突出的固定凸缘之间的密封表面处避免空化。 紧固凸缘连接到远离压力管路的阀壳体的端部上的圆筒形部分,该压力管线通向注射喷嘴,并且密封件装配到圆柱形部分和螺纹连接元件的内壁之间的中间室中。 该密封构件被至少一个环形接触表面按压到圆柱形壳体部分上,并且具有相对于第一孔轴向移位的不同接触表面被压靠在螺纹连接元件上。 密封构件可以被实施为薄壁的金属薄板套管,可以包括螺旋弹簧,或者可以由塑料制成。

    • A fuel injection pump for Diesel engines in which a rotating and reciprocating piston pressurizes and distributes fuel to individual pressure lines leading to the injection valves of the engine. In order to change the timing of injection with respect to the engine cycle, there is provided a mechanism to change the relative angle between the pressurizing piston and its drive means, which runs in synchronism with the engine. The mechanism operates hydraulically and is affected by the fuel pressure in the sump of the injection pump. There is also provided a hydraulic control valve mechanism which permits varying amounts of fuel to flow back from the sump to the low pressure side of the fuel delivery pump, thereby changing the injection timing. A primary control valve adjusts the sump pressure on the basis of engine speed while a secondary control valve adjusts the sump pressure on the basis of engine temperature in order to adapt the timing of fuel injection to engine starting and engine warm-up. Various embodiments are presented.
    • 一种用于柴油发动机的燃料喷射泵,其中旋转和往复活塞将燃料加压并分配到通向发动机的喷射阀的各个压力管线。 为了改变相对于发动机循环的喷射时间,提供了一种改变加压活塞与其与发动机同步运行的驱动装置之间的相对角度的机构。 该机构液压操作并受到注射泵的油槽中的燃料压力的影响。 还提供了一种液压控制阀机构,其允许不同量的燃料从燃料输送泵的贮槽向低压侧回流,由此改变喷射正时。 主控制阀基于发动机转速来调节油底壳压力,而二次调节阀根据发动机温度来调节油底壳压力,以便使燃料喷射的时间适应于发动机起动和发动机预热。 呈现各种实施例。
