ABSTRACT:
An rpm regulator for fuel injection pumps of internal combustion engines having a starting lever, which is coupled on one side with a fuel quantity setting member and on the other side with an rpm governor, which contacts the starting lever with an rpm dependent force in opposition to an arbitrarily variable force of a main control spring, which is included in series with the main control spring and is deformable up to a first stop. A further spring, also deformable up to the first stop, is provided parallel to the starting spring for the purpose of adaptation of the fuel injection quantity. It is proposed to provide a second stop in addition to the first stop, at least in the full load range, by means of which the starting lever can be blocked in the direction of the first stop from the time an adaptation rpm is attained and before it reaches the first stop. By utilizing such an internal combustion engine in a vehicle, a smooth driving mode is attained because a positive adaptation can be switched off by means of the second stop in the full load range and thus is not effective in that range. The adaptation of the fuel injection quantity in the partial load range, however, is fully retained.
