    • A fuel injection pump for internal combustion engines, which has a pump interior and a control mechanism chamber separate from it, with a control mechanism for actuating a quantity adjusting device determining the fuel injection quantity, is provided with an electrical temperature sensor, to compensate for the effect of temperature on the metered fuel quantity. The output signal of the temperature sensor is included as a correction variable in the control variable for the control mechanism. To assure accurate temperature measurement without delay, and for easy access to the temperature sensor for servicing, the temperature sensor is disposed in the control mechanism chamber and, with a temperature-sensitive sensor element, preferably an NTC resistor, dips into a permanent fuel flow diverted from the pump interior. The electrical connecting lines of the temperature sensor are extended to a circuit board on which the connecting lines for the electric control mechanism are also located, in the control mechanism chamber and bonded thereto.

    • A fuel injection pump for internal combustion engines that has a pump interior and a final control element chamber, separated from it, the latter having an electric final control element for actuating a quantity adjusting device that determines a fuel injection quantity, parts of the final control element from which a control variable for the injection quantity is derived and which thereby serves as a material measure, are to be protected from the influence of fuel. By means of a jet pump through which a permanent propulsive flow flows and which is part of a flow conduit, the static pressure at the intake bore of the jet pump that communicates with the final control element chamber is lowered, and this negative pressure is utilized for evacuating the fuel entering the final control element chamber in the form of a leakage flow along the bearing of a control shaft. This arrangement is particularly suitable for high-pressure injection in Diesel engines, to attain highly accurate fuel metering that is stable over a long period of time.

    • A fuel injection pump having a cam drive and an injection adjuster piston, acting on the cam drive and serving the purpose of an injection onset adjustment. The injection adjuster piston on a face end encloses at least one pressure chamber that via a control valve is either made to communicate with a pressure source or a relief line or can be closed entirely. The control valve is actuated by an a proportional electromagnet. As a result, only a little adjusting medium is required, to obtain a high efficiency of the injection onset adjustment, and advantageously the injection adjuster piston is stressed only axially, and frictional forces on the circumference of the injection adjuster piston are thus avoided.
    • 一种具有凸轮驱动器和喷射调节器活塞的燃料喷射泵,其作用在凸轮驱动器上并用于喷射开始调节的目的。 至少一个压力室包括至少一个压力室,压力室通过一个控制阀与压力源或溢流管连通,或者完全关闭。 控制阀由比例电磁铁驱动。 结果,仅需要一点调节介质,以获得喷射开始调节的高效率,并且有利地,喷射调节器活塞仅在轴向受到应力,因此避免了喷射调节器活塞的圆周上的摩擦力。
