Abstract
An apparatus which serves to actuate the throttle valve of an internal combustion engine of a motor vehicle. The actuating device includes a reversible electric drive motor, the output shaft of which is operatively connected to the throttle valve, which is pivotable via a throttle valve shaft. The set-point pivoted position of the throttle valve can be predetermined by means of a gas pedal. A simple, economical design of such an actuating device is attained by coupling the throttle valve to a stop such that they rotate together; associated with the stop is a counterpart stop that is spring-loaded in the closing direction of the throttle valve by a restoring spring. The counterpart stop is coupled with the gas pedal in such a way that it is moved by the drive lever counter to the force of the restoring spring.
