Abstract: A control device in which if the control device fails the throttle valve reaches an emergency operation position by use of only one spring. If the control device fails, the single spring can move a throttle valve to an emergency operation position, located between two terminal positions. This is achieved by various-sized speed-changing gears between the two spring connections and an intermediate member. No additional spring is needed for this. The control device is suitable particularly for vehicles that have a throttle-type internal combustion engine.

Abstract: A throttle control valve in which potentiometer paths of a potentiometer are mounted on the lid and an electrical motor coupling is also provided, so that when the lid is attached to the throttle valve stub, the potentiometer and the control motor can be connected by simple joining in a single operation. The throttle control valve is intended for internal combustion engines for motor vehicles.
