Abstract
The governor (FIG. 1) includes a second idling spring (supplementary idling spring 42) secured on a force transmission lever (31) acted upon by the main governor spring (34). By means of the second idling spring, the restoring force of a first idling spring (38) on a portion of the idling sleeve path (a) is reinforced in the idling position of an adjusting member (22). This exertion of force on the part of at least the supplementary idling spring (42) is increased in accordance with load by means of a corrective adjusting member (44) when the adjusting member (22) has pivoted into a partial-load position. As a result, in order to improve the starting behavior even in minimum-maximum speed governors, a partial-load rpm located above the idling rpm can be regulated, and a progressively increased supply quantity is controlled at the associated injection pump with increasing load in the lower partial-load range.
