Abstract

Tubo di aspirazione a combustione interna, comprendente un corpo (1) di forma stabile con almeno una prima apertura di passaggio 82), in cui nella prima apertura di passaggio (2) è disposto almeno un primo elemento di regolazione (3) per variare la sezione trasversale di flusso, che consiste di una valvola a farfalla (5), supportata in modo girevole nel corpo (1) del tubo di aspirazione e atta ad essere impegnata a tenuta con la parete di delimitazione (4) della prima apertura di passaggio. Il corpo (1) del tubo di aspirazione presenta nella zona della valvola a farfalla (5) almeno una seconda apertura di passaggio (6), che è coordinata quale bipasso alla prima apertura di passaggio (2), la seconda apertura di passaggio (6) essendo chiudibile mediante almeno un secondo elemento di regolazione (7), che è formato da una valvola a una sola via (8) spostabile alla posizione di apertura solo in direzione del motore a combustione interna ad essa collegato.
