ABSTRACT:
In an arrangement for regulating the idling speed of rotation of an internal combustion engine by influencing the intake by means of an electromagnetic control element, a ferromagnetic actuating element is provided within the field of influence of a solenoid. There also acts on the actuating element an auxiliary spring which moves a valve element against the force of a return spring in order to establish an average rate of flow of air when the solenoid is without current. If the solenoid is acted on by current, the actuating element is moved away from a stop so that the valve element can adjust itself only under the influence of the force of the solenoid and of the return spring.
