Abstract
A centrifugal adjuster for a fuel injection pump governor having a driving part driven at an rpm in synchronism with the engine and having a torsionally elastically coupled flyweight holder guided in a rotational guide. Via a step, beyond a predetermined rotational deflection, the centrifugal adjuster displaces the flyweight holder axially with respect to the driving part, so that a jolt-like stroke effected by means of the step is superimposed on the regulating stroke effected via the flyweights of the centrifugal adjuster whenever the rpm is at a low level, for instance at idling rpm. As a result, a friction that leads to see-sawing of the engine and exhibits pronounced hysteresis is shaken out of the governor.
