Abstract

Per il montaggio di una disposizione di valvola a farfalla (12) nella conduttura (11) dei gas di scarico è praticata un'apertura (20) radiale, a forma di fessura, con allargamento (21) centrale cilindrico, attraverso il quale la disposizione (12) di valvola a farfalla, come gruppo costruttivo completo, è inseribile, con il disco valvolare (14) in avanti, orientato parallelamente rispetto alla direzione assiale della conduttura (11) dei gas di scarico, attraverso l'apertura radiale (20), dentro nella conduttura (11) dei gas di scarico. In tal modo è possibile il montaggio di un organo di chiusura (13), chiudente a tenuta, senza separazione parziale della conduttura (11) dei gas di scarico.(Figura 1).
