Abstract

The device controls a throttle member of an induction passage in a fuel supply system. It comprises a first electric sensor for delivering a signal representing the position of a driver actuated member, an electric actuator and a second electric sensor providing an electric signal representing the actual position of the throttle member. The actuator and the sensor are mechanically connected to the throttle member. An electric control circuit receives signals from the sensor and gives the throttle member a position which depends on the position of the driver actuated member. A movable stop is mechanically connected to the driver actuated member and has a one-way connection with the throttle member which limits its degree of opening.
