Weights are moved to the periphery by the centrifugal force and thus
axially shift a mobile bell connected to the injection pump rack control
lever by a linkage.
A spring placed under tension by the accelerator control offset the
weight centrifugal force.
Balance between the two forces keeps speed at an almost constant
level in spite of load variations.
 See page 62 for timing.
