  • Patent number: 4913633
    Abstract: 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.

  • Patent number: 4840161
    Abstract: A fuel injection pump for internal combustion engines, in particular having a plurality of linearly aligned pump elements, the pump injection onset is determined by one control slide per pump element in which the control slide is axially displaceable on the pump plunger and by a control of relief conduits of the pump work chambers. The control slide is actuated via a torque shaft in that a respective adjusting bolt of a straddling element joined to the torque shaft engages a cross groove of the control slide. The adjusting bolt has a cylindrical stud portion and a slide shoe supported thereon, and the slide shoe is secured against axial displacement by means of a head of the adjusting bolt.
