Abstract

A centrifugal rpm governor for fuel injected motor vehicles, in which the control stroke, which is detected by a lever controlled follower on an adapting surface, is enlarged for a more precise control of the adaptation. A translated shift lever is used as the control lever, which is coupled with the governor adjusting member and the lever carrying the follower. To improve the quality of the governor, the shift lever engages an adapting lever, which carries the follower and which is arranged nearly parallel to the intermediate lever. By means of an adjusting member, which is provided with an adapting control and retraction spring, and which is separated in the governor and adapting sleeve, the use of the governor as an idling as well as a maximum rpm governor is made possible.
