The guide-lever, the floating-lever and the link will push the control-rack to the full-load
position by transferring the action to the lever_
To transfer the control-rack to the full-load position, it is enough to move the
control-lever slightly from the idling position. Then the ungleich-spring in the tension lever
(if the spring is involved in it) becomes effe..."1:ive. The injection pump supplies much fuel to
the cylinder of engine and the r.p.m. rises. As soon as the centrifugal force exceeds the
tension of the governor-spring, the flyweight will spread itself outside and pulls back the
guide-bush, shifter, floating-lever and the control-rack in the direction of "fuel decrease".
The r_p.m. of the engine will not rise from this point and it is maintained by the governor
under a fixed condition.
When the control-lever is transferred to the position of the highest r.p.m. (Fig. 7), the
governor works as shown in the Fig. 6 as aforesaid_

In this case, the swivel-lever of course stretches the governor-spring fully. Accordingly
the governor-spring stretches the tension-lever with its large-power to the full-load stopper
and transfers the control-rack to the full-load position. The r_p.m_ of the engine rises and the
control r.p.m. and the centrifugal force also increase.
