Abstract
A governor for fuel injection pumps, said governor having two or three cooperating levers used to move a fuel injection quantity control slide. A regulating spring and the idling spring engage the drag lever. A start spring is disposed between the drag lever and the start lever, the start spring is opposed by the force of a flyweight assembly which is speed-dependent. When starting the combustion engine, the start lever, which is connected to the drag lever via a pivot pin, is in an initial position corresponding to a setting of the quantity control slide, which setting is smaller than the full injection quantity. When starting, the quantity control slide is displaced through a first control range to deliver a greater quantity of fuel, up to the full load injection quantities. Thereupon, when instituting a decrease, further displacement of the flyweight assembly results in the quantity control slide being displaced through a second control range in the direction of smaller quantities of fuel.
