<p>The device (1) has a radially external tubular cover comprising an inlet end fitting (3) and an outlet end fitting (4) for fluid respectively terminated in peripheral extensions (5, 6) welded to each other by a welding interface (7). A flange (14) comprises a radial annular partition (14a) for separating annular resonance chambers (12, 13). A radial partition is axially displaced towards one of the extensions of the inlet end fitting opposed to the other extension towards which an edge is extended, where the latter extension is widened while truncating.</p> |
