ABSTRACT:
A device that serves to actuate a throttle valve. The actuating device includes an electric drive motor and a step-down gear driven by the motor; an output shaft of the step-down gear is operatively connected to a throttle valve shaft which controls the throttle valve. The actuating device is compact in structure as well as versatile in use, even with various sizes of throttle valve, the step-down gear is embodied as a planetary gear having its output shaft provided with a gear wheel, which is operatively connected via a toothed belt with a second gear wheel, disposed on the throttle valve shaft. The motor is controlled by a control means assembled in the same housing as the motor and the throttle valve.
