Abstract
A device for the control of the position of an element of an internal combustion engine which influences the fuel-air mixture, particularly for the rotational speed control, which element is coupled with a servomotor, the latter being fed by the output of a differential amplifier, whereby an actual value input of the differential amplifier is in connection with an actual value transmitter and a desired value input of the differential amplifier is connected with a desired value transmitter. A diode is arranged from the desired value input to the actual value input connected in the forward conducting direction, and a resistor is connected between the junction point of the desired value input with the diode and the desired value transmitter.
