ABSTRACT:
An apparatus for setting the angular relationship between rotating driving, and driven members in the injection pump drive of an internal combustion engine. The driving member and the driven member have a toothed portion of which at least one is a helical toothed portion, whereby the toothed portions are coupled to each other by a coupler member having toothed portions which mesh with the toothed portions of the driving and driven members. At least one of the toothed portions of the coupler member is configured as a helical portion and is hydraulically displaceable with respect to the other toothed portions. This hydraulic displacement is controlled by a centrifugal governor having flyweights. The flyweights displace a valve member against the force of at least one spring in an rpm-dependent manner to effect the rpm-dependent adjustment of the instant of injection. In addition to the rpm-dependent displacement, a load-dependant displaceability, can be superimposed. As a result, the instant of injection can be influenced in accordance with load, in order thus to attain an improved combustion efficiency.
