Abstract
La capacità interna (3) di un collettore di aspirazione (1) comunica con ciascuna uscita (5) del collettore che conduce ad un cilindro del motore tramite un primo condotto (7) ed un secondo condotto (8) più lungo del primo condotto (7) e disposto in parallelo ad esso. Al di sotto di un valore di soglia predeterminato del numero di giri del motore, il primo condotto (7) viene ostruito da un otturatore (17) a tenuta frontale cooperante con una superficie piana di tenuta (21) costituita da una superficie che delimita la capacità interna (3) sulla quale sfocia il condotto principale (7) e che costituisce parte della superficie di accoppiamento di due elementi componenti il corpo del collettore.(Figura 1).
