Abstract: A centrifugal rpm governor, intended in particular for Diesel vehicle engines, is proposed, by means of which the supply quantity adjustment member of the injection pump is held in the stop position after the engine has been turned off, in order to prevent unauthorized and unintended starting of the engine. The governor is provided with a shut-off lever held in its operational position by a tension spring and by which lever the supply quantity adjustment member of the injection pump is displaceable into its stop position. The tension spring is embodied as a holding spring and so disposed that the shut-off lever both in its operation position and its shut-off position is drawn into the pertinent terminal position and held there. To this end, the force of the holding spring is greater than the force of a deviation spring attached to the control linkage.

Abstract: A centrifugal governor is proposed for fuel injected internal combustion engines, which preferably functions as an idling and a final rpm governor. Preferably, the governor is provided with a cam-guided adaptor apparatus whose influence on the governor movement is removed in order to increase the work capacity of the governor during idling operation. The centrifugal rpm governor includes an intermediate lever connecting a governor sleeve with the control rod of an injection pump. The intermediate lever is additionally actuatable by a setting lever, and an adaptor lever system. The adaptor lever system substantially comprises an adaptor lever disposed approximately parallel to the intermediate lever and cooperating therewith and actuatable by the governor sleeve. The adaptor lever has at its outermost end a cam follower, which is guided on a cam surface of a stop cam for the purpose of limiting the full-load supply quantity.

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.
