ABSTRACT:
A centrifugal speed governor for controlling fuel pump discharge into an internal combustion engine has a control shaft rotatable and axially movable by the rotation and radial movement of fly weights, respectively. The control shaft is operatively associated with a fuel pump control rack so that the pump discharge is varied with the increase of the engine speed. A maximum fuel lever having one end operative to limit movement of the control rack toward increasing the pump discharge in high speed engine operating range is operatively associated, at a point between the ends, with the control shaft and is pivotally connected at the other end to one end of a holding lever which is pivotally connected at the other end to the governor casing. The holding lever is operatively associated at a point between the ends with the control shaft so that the holding lever is held stationary in low speed engine operating range and also in compensation engine operating range between the low and high engine operating ranges but is rotated by the axial movement of the control shaft in the high speed engine operating range either to allow the control rack to be moved within a limited and reduced range toward increasing the pump discharge, or to move the control rack toward decreasing the pump discharge.
