Abstract
In a centrifugal rpm regulator for fuel injected internal combustion engines, a fuel quantity control rod is provided which receives the forces associated with the displacements of an adapter sleeve which, in turn, is displaceable under the influence of centrifugal flyweights and as a function of engine rpm. The regulator also includes an idling control spring, a maximum rpm control spring and an adapter stop having an adaptation spring, with the adapter sleeve comprising two mutually coaxially disposed portions and an intermediate spring therebetween. The pretension force of the intermediate spring is greater than the maximum force of the idling control spring and the pretension force and spring stiffness of the intermediate spring are smaller than the pretension force and spring stiffness of the adaptation spring.
