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. When the setting lever is located in the idling position, the adaptor lever system is separated from the governor sleeve by means of a back-off lever. As a result, the adaptor lever system has no influence on governing during the idling operation. The back-off lever is advantageously connected with the setting lever in a rotationally secure manner and is preferably supported together with a bell crank connecting the adaptor lever with the governor sleeve on a common lever shaft in the governor housing.
