ABSTRACT:
A governor mechanism for controlling the setting of a fuel control member of a fuel pump includes a first lever located about a pivot. One end of the first lever is connected to the fuel control member and the first lever is urged in a direction to reduce the fuel delivered by a centrifugal mechanism. A second lever is engageable by the first lever and is urged in a direction to increase the amount of fuel delivered by a pre-stressed governor spring. The extent of movement of the second lever by the governor spring is limited by a maximum fuel stop and the pivot of the first lever is resiliently located by a spring which as the speed increases allows the pivot to move to increase the maximum amount of fuel which can be supplied by the fuel pump.
