摘要： A fuel injection pump, with an injection adjusting piston that serves to adjust the onset of injection, in which due to an off-center coupling to a cam part of the cam drive of a fuel injection pump embodied as a distributing injection pump, the injection adjusting piston is subjected to tilting moments during operation. In addition, the injection adjusting piston is subjected to other forces by means of a radially produced pressure fluid supply on a side of the injection adjusting piston disposed essentially opposite the coupling, and these other forces, together with the tilting moment forces, produce high, one-sided pressure loads in the radial direction on the injection adjusting piston. By producing a second pressure field, the injection adjusting piston undergoes a compensation of the above-mentioned forces acting on the injection adjusting piston and consequently experiences a significantly reduced radial load.

摘要： A fuel injection pump for adjusting the injection onset by an injection adjuster piston. The piston is embodied as a follower piston of a control slide disposed in the piston on one side the piston encloses a work chamber and is acted upon by the pressure in this work chamber counter to the force of a restoring spring, and is connected to a substantially stationary part of a cam drive of the fuel injection pump. To avoid feedback of pressure surges on the control slide and its adjustment, the inlet cross section of the connecting line is embodied as an elongated cross section extending in the displacement direction of the control slide. A more problem-free adjustment of the control slide is thus obtained, and hence also a more-precise, vibration-free adjustment of the injection adjuster piston and of the injection onset is obtained.

摘要： A fuel injection pump for internal combustion engines which has a moving part supported in a housing bore and on its jacket face on one side, has an exit opening that is under high pressure, and whose bearing is improved by virtue of the fact that on the jacket face of the part or in the wall of the housing bore, at least one pressure compensation is provided. The compensation face is connected to a high pressure source, is disposed on a side of the jacket face of the part which side is remote from the exit opening, and is continuously covered by the wall of the housing bore. As a result, a compensation of the pressure action by means of the pressure field prevailing in the region of the exit opening occurs so that an improved, less damage-prone bearing is produced with a greater high pressure tightness of the moving part.

摘要： 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.

摘要： 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.

摘要： A fuel injection pump for internal combustion engines, which includes at least one pump piston driven by a cam drive mechanism to carry out a feed stroke and an intake stroke. The pump includes a fuel filled storage chamber that is under storage pressure and is for aspirating fuel in the intake stroke and for feeding excess fuel at the end of the feed stroke to a tank. A fluid filled drive mechanism chamber under lubrication pressure, contains the cam drive mechanism and is divided from the intake chamber by a movable wall. A vacuum chamber is disposed in the fluid filled drive mechanism chamber in order to damp pressure oscillations in the drive mechanism chamber, the vacuum chamber is at least partially defined by a membrane that is acted upon by the lubrication pressure. The rigidity of the membrane is designed so that its effectiveness comes into play only when there is a pressure load that is slightly greater than the stationary lubrication pressure in the drive mechanism chamber (22).

摘要： A fuel injection pump for internal combustion engines having an electromagnetic final control element, which in order to adjust the end or onset of injection engages a control slide, located in the pump interior. Via a control shaft, the final control element chamber is hermetically sealed off from the pump interior in order to keep water contained in the fuel from reaching current-carrying parts of the final control element. As a result, fluid communication exists only via the bearing gap of the slide bearing of the control shaft and the bearing gap functions as a throttle. The throttle forms a water separator, which further reduces the concentration of water in the already small quantity of fuel reaching the final control element chamber through the throttle.
