ABSTRACT:
A speed governor of a fuel injection pump for internal combustion engines is proposed, having a governor lever for adjusting the fuel injection quantity and a governor spring assembly engaging the governor lever counter to which assembly an rpm-dependent force acts. To compensate for manufacturing tolerances in the governor spring assembly, it is proposed that the effective length of a prestressed governor spring in the governor spring assembly be effected by means of the rotation of a spring plate, in that the spring plate has a sleeve provided with an outer thread, onto which part the governor spring can be threaded. After the rotation of the spring plate, this plate is held in its terminal position, under the influence of the initial stressing force of the governor spring, in a positively engaged connection with intermeshed components which limit the relieving of the governor spring assembly in the other direction.
