ABSTRACT:
A centrifugal rpm regulator for the fuel injection pump of an internal combustion engine is equipped with a separate, independent, rpm-responsive adjustment mechanism which rotates a cam. This cam serves as the limiting stop for a lever which controls the injected fuel quantity and it determines the maximum injected fuel quantity. The cam is linked to a plunger which is actuated by rpm-dependent fluid pressure. Axial motion of the plunger results in rotation of the cam. The cam is mounted on a pin which is affixed eccentrically and adjustably within the regulator housing.
