The angleich spring is mounted to the part of the tension lever (however some engine are not equipped with an angleich spring depending on usage and speed range utilized). When engine speed is low, the governor weight cannot compress the angleich spring as the angleich spring load is lager than the governor weight, thrust load, and the control rack is held at a position (R c ) to increase injection volume. Furthermore, as engine speed rise, the angleich spring is gradually compressed as governor weight thrust load increases and exceeds angleich load, before high speed control is effected.
When the governor lever and the bottom of the tension lever come into contact (end of angleich stroke), injection volume is reduced by that amount, and the rack reaches the rated position (R E ). 14
