Abstract

A speed governor for injection pumps in internal combustion engines with a regulating sleeve which at maximum rotational speed of the internal combustion engine is displaced as a function of speed within the regulating sleeve travel against the force of the main regulating spring that acts on a force transmitting lever. The regulating movements of the force-transmitting lever are transmitted onto the fuel delivery adjusting member of the injection pump by means of at least one intermediate lever. The internal combustion engine rotational speed can be influenced by means of an operating element adapted to be controlled. In case of a needed change of the beginning of the full-load speed regulation of the internal combustion engine, the spring travel of the main regulating spring is influenced by means of a force-transmitting element.
