Abstract
I compressori (16, 17) dell'aria di alimentazione si trovano in permanente accoppiamento motore con una turbina (15) dei gasi di scarico che non può essere disinserita durante i periodi di esercizio del motore endotermico. Il comando dello stato di manovra, alimentazione a vuoto oppure esercizio di mandata, di un compressore (16, 17) dell'aria di alimentazione avviene per mezzo di un dispositivo di commutazione (20) controllante il bocchettone di mandata. Per migliorare il rendimento del gruppo di sovralimentazione (12) viene minimizzato l'assorbimento di potenza del compressore (16, 17) dell'aria di alimentazione, di volta in volta momentaneamente impostato sull'alimentazione al minimo, influenzando la portata della massa d'aria ancora presente
