摘要： A flexible duct (1) for interposing between the exhaust manifold of the engine of a motor vehicle and the subsequent exhaust pipe so as to decouple them from each other, constituted by a flexible tubular element (2) with a continuous double wall (7), a pair of sleeves (12) fixed on the ends (3;4) of the tubular element and a pair of collars (14) arranged outside the ends of the tubular element so as to hold this to the sleeves; the tubular element is made of two superimposed sheets (5;6) of stainless steel, bent into a closed tube and deformed axially so as to form a series of circumferential corrugations which provide flexibility; the two sheets (5;6) are of different thickness, the inner one being thicker than the outer; this arrangement provides greater reduction of the noise typical of a corrugated pipe and also damps the noise of the engine; in addition, it increases the fatigue resistance to stresses and the rigidity of the flexible duct compared to similar pipes with a double wall of the same overall thickness made up of two walls each of the same thickness.
