  • Patent number: 5226794
    Abstract: A fuel injection pump having a pump piston in a bore of a pump cylinder, wherein the pump piston is rotatable for fuel control, and having a niche disposed in the pump cylinder for receiving a control slide, wherein the niche can be made by non-cutting shaping. The niche has a flat niche bottom, which changes into two oblique niche walls, which extend in two straight parallel niche walls facing one another, these parallel niche walls in turn, change into oblique faces and terminate in slideways, in which the control slide is guided against twisting by slide runners that simultaneously act as impact aprons. The niche is embodied by non-cutting shaping in such a way that its wall thickness relative to the cylindrical outer shape of the pump cylinder is embodied as virtually constant.

  • Patent number: 4989571
    Abstract: A fuel injection pump for internal combustion engines having housing with a plurality of in-line pump elements including pump cylinders, surrounded by separate suction chambers and communicating with them by means of overflow openings, having two primary conduits disposed parallel to a camshaft for the inflow and outflow of fuel to and from the separate suction chambers and having defined connecting conduits between each separate suction chamber and each primary conduit by means of which the same quantity of fuel is metered to all the separate suction chambers under the influence of a pressure drop produced by the connecting conduits wherein an inflow connecting conduits has one fuel inflow throttle insert for the fuel inflow primary conduits the throttle insert being closed at one end and discharges with its open end into the separate suction chamber with its closed end protruding into the fuel inflow primary conduit the throttle insert having a defined throttle opening for conducting fuel from the primary c

  • 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.
