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 having a plurality of pump elements disposed in a row, the onset and end of supply of each being effected by means of a respective control slide that is axially displaceable on the pump piston and by the control of relief conduits for the pump work chamber. The control slides are actuated via a rotary shaft; upon rotation of the rotary shaft, the control slides are axially displaced via driver arms secured on the rotary shaft. To adjust the axial position of the individual control slides relative to one another, the driver arms are permanently deformed in the axial direction of the control slides.

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 includes an injection onset adjustment piston in a cylinder bore that adjusts injection. The onset adjustment piston is embodied as a following piston which includes therein a control slide valve. The onset adjustment piston encloses a work chamber on one end, and is acted upon by the pressure in the work chamber counter to the force of a restoring spring. The onset adjustment piston is connected to an essentially stationary part of a cam drive of the fuel injection pump. In order to prevent feedback from the work chamber via the control slide valve and its adjustment, the control slide valve is effectively damped by means of a separate pin on an end of the control slide valve which extends into a blind bore of the onset adjustment piston.
