ABSTRACT:
An apparatus for the rpm-dependent adjustment of the timing of an injection pump for internal combustion engines (shaft-type injection adjuster), in which a rotationally driven primary part is connected in a rotationally coupled manner with a secondary part but with the rotational angle between them being variable. The connection is effected via an axially displaceable sliding sheath, which is positively connected via at least one of the parts via a bevel gear and simultaneously acts as an adjusting piston. The working face of this adjusting piston is supplied with a control pressure by a centrifugal force control piston supported in a separate transverse bore in the primary part, either directly or with the intermediacy of an additional control piston, with respect to which then the adjusting piston effecting the coupling between the driving part and the driven part is embodied as a followup piston. A central, inner shaft, which is supported in the driving part and driven part, assumes the function both of guiding the adjusting piston and the control piston disposed in the interior thereof and of supplying the pressure medium.
