An rpm governor of a fuel injection pump for internal combustion engines is proposed. The rpm governor includes a governor spring, which at one end engages a governor lever of the fuel injection pump and at the other end engages a correction lever. The other end of the correction lever is engaged by a correction spring, which is coupled at its other end with an adjusting member secured eccentrically relative to an adjusting shaft on an adjusting lever. The adjusting lever is connected with the adjusting shaft and is variable in its position by means of this shaft. The correction lever is supported between a roller and an adjusting gear wheel, which engages a rack zone of the correction lever. By rotating the adjusting gear wheel, the lever arms associated with the governor spring and the correction spring can be varied, thus varying the resultant spring force or spring constant engaging the governor lever in order to establish the degree of proportionality of the rpm governor.
