In an rpm regulator for fuel injection pumps of internal combustion engines having a starting lever, which is coupled on one side with a delivery quantity adjustment member of the injection pump and on the other side of which an rpm tachometer contacts the starting lever with an rpm-dependent force counter to an arbitrarily variable force of a main regulator spring and also counter to the force of a starting spring which is included in series with the main regulator spring and deformable up to a particular stop, it is proposed to provide a further stop which urges the starting lever counter to the direction urged by the starting spring, whereby this second stop is adjustable in accordance with the temperature in order to regulate the starting quantity. The temperature of the coolant, of the lubrication oil, as well as that of a housing wall of the internal combustion engine may be employed for this purpose. It is also possible to employ the temperature of the inner chamber of the regulator of the injection pump itself as the regulatory value. By employing a stop element which is adjustable in accordance with temperature, the starting quantity may be increased during either cold or hot starting, since there are engines which require an increased starting quantity not only at low temperatures but also at extremely high temperatures.
