摘要

The system described enables, in the event of failure of the electric actuator (13) on the throttle (11) or of the control or power supply to said actuator, operation in the emergency mode and prevents in a reliable manner the blocking of the throttle (11) in a rest position. A return spring (15) is provided which is permanently meshed with the shaft (12) of the throttle and a preloaded opposing spring (21) with partial meshing with said shaft (12), said springs co-operating with an electromotive actuator (13).
