The carburettor venturi (3) has a flap (4) which is driven by an electric motor (8) via a transmission (7). The transmission slips in order to interrupt the drive train, if the torque of the engine exceeds a predetermined value. One gearwheel (10 or 12) may be connected to a shaft (14) via a sliding clutch (13). This may be a large gearwheel (10) of a double gearwheel set, which is connected to the shaft (15) of a smaller gearwheel (12), via a sleeve (16). The sleeve may also be a spring-loaded band, which has a wave-like contour. |
