GOVERNOR MECHANISM and OPERATION
1. Mechanism
The governor is centrifugal flyweight type, which means a flyweight is fitted to the governor gear. The governor sleeve is as-
sembled so that it may slide toward the direction of the axis of the pump shaft, and it is in contact with the flyweight. The
governor sleeve gets in touch with the governor yoke, and through the governor lever it makes the control rack of injection
pump operate. This mechanism enables t o maintain constant operation irrespective of load variation.
