Abstract

Il sistema regola la portata d'aria in un corpo farfallato (1) di un dispositivo di alimentazione per un motore endotermico di un veicolo, e comprende primi mezzi (8) che comandano la posizione angolare di una farfalla (2) installata nel corpo, fra una posizione di minima apertura e viceversa, posizione angolare che presenta una angolazione positiva rispetto ad un piano trasversale (C) sul quale giace l'asse di rotazione della farfalla. Il sistema comprende secondi mezzi (12, 13) di comando, in caso di mancato funzionamento dei primi mezzi, di una posizione angolare della farfalla con una angolazione negativa rispetto al piano trasversale in modo da determinare una portata d'aria che fluisce lungo il corpo sufficiente a definire un regime accelerato del motore endotermico.The system regulates the air flow in a throttle body (1) of a supply device for an internal combustion engine of a vehicle, and comprises first means (8) which control the angular position of a butterfly (2) installed in the body, between a minimum opening position and vice versa, an angular position which has a positive angle with respect to a transverse plane (C) on which the rotation axis of the butterfly lies. The system comprises second means (12, 13) for controlling, in the event of failure of the first means, an angular position of the butterfly with a negative angle with respect to the transverse plane so as to determine an air flow rate flowing along the body sufficient to define an accelerated speed of the internal combustion engine.
