Title
(EN) SYSTEM FOR REGULATED DOSING OF COMBUSTION AIR INTO AN INTERNAL COMBUSTION ENGINE
(FR) SYSTEME POUR LE DOSAGE REGULE D'AIR DE COMBUSTION DANS UN MOTEUR A COMBUSTION INTERNE
Abstract
(EN)
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).
(FR)
Le système décrit autorise, en cas de défaillance de l'actuateur électrique (13) sur l'étrangleur (11) ou de la commande ou encore de l'alimentation en courant dudit actuateur, un fonctionnement en régime de secours et empêche de manière fiable un blocage de l'étrangleur (11) dans une position de repos. Il est prévu un ressort de rappel (15) à engrènement permanent avec l'arbre (12) de l'étrangleur et un ressort antagoniste (21) précontraint à engrènement partiel avec ledit arbre (12), lesquels ressorts coopèrent avec un actuateur (13) électromoteur.
