有した噴射ポンプ用ガバナ。A rotation speed detection sensor that detects the engine rotation speed, a rack position detection sensor that detects the position of the control rack of the injection pump, and an injection amount detection sensor that detects the injection amount of the injection pump or a torque that detects the torque of the engine. The injection amount or torque displacement ratio per unit displacement of the engine rotational speed is calculated based on the detection sensor and the output signals of the three sensors mentioned above, and in the steady rotation range where the calculated value is smaller than the set value, it is suitable for this range. rack position signal,
Conversely, in a transition rotation region where the calculated value is larger than the set value, there is a rotation region setting means that outputs a rack position signal suitable for this region, and a control rack is placed at a rack position according to the rack position signal from this rotation region setting means. A governor for an injection pump having a rack control means for moving it to obtain a desired injection quantity or torque.
