Nowif the engine is heavily loaded, the throttle valve must be wide change of opening is obtained by a variation in the height of thegovernor, which is caused by a change of speed. Thus it is seen thatthe governor can control the speed only within certain limits whichare not far apart. The difference in the extreme heights of the gov-ernor must be sufficient to open the throttle its entire range.
