Zusammenfassung:	A volumetric assembly includes: a roots-type supercharger device; a roots-type expander device; a first duct extending from the supercharger fluid inlet, the first duct supplying fluid to the roots-type supercharger device; and a second duct extending from the expander fluid outlet, the second duct directing fluid away from the roots-type expander device, wherein the first duct is positioned adjacent to the second duct, and wherein the first duct defines a first aperture and the second duct defines a second aperture, the first and second apertures being generally aligned; and a flexible membrane positioned between the first and second ducts in the first and second apertures, the flexible membrane sealing the first duct from the second duct, and the flexible membrane flexing as fluid flows within the first and second ducts to attenuate noise associated with the fluid flows. L'invention porte sur un ensemble volumétrique, qui comprend : un dispositif de compresseur Roots; un dispositif de détendeur Roots; un premier conduit s'étendant de l'entrée de fluide de compresseur de suralimentation, le premier conduit fournissant un fluide au dispositif de compresseur Roots; et un second conduit s'étendant de la sortie de fluide de détendeur, le second conduit dirigeant le fluide à l'opposé du dispositif de détendeur Roots, le premier conduit étant placé de façon adjacente au second conduit, et le premier conduit définissant une première ouverture et le second conduit définissant une seconde ouverture, les première et seconde ouvertures étant sensiblement alignées; et une membrane flexible positionnée entre les premier et second conduits dans les première et seconde ouvertures, la membrane flexible isolant hermétiquement le premier conduit du second conduit, et la membrane flexible fléchissant lorsqu'un fluide s'écoule dans les premier et second conduits pour atténuer un bruit lié à l'écoulement de fluide.
