Title (EN) SOUND ATTENUATOR WITH IRREGULAR ARRAY OF INTERNAL DUCTS
(FR) SILENCIEUX AVEC RÉSEAU IRRÉGULIER DE CONDUITS INTERNES
Abstract:
(EN) A sound attenuator (1) comprises a fluid inlet (3)and a fluid outlet (4) disposed along a main axis (10), and a plurality of fluid transmission ducts (6, 7, 12, 13, 14) extending between the fluid inlet (3) and outlet (4). The ducts are surrounded by a sound-absorbing material (9), and they are disposed at respective positions relative to the main axis (10), whereby the separation between at least one pair of adjacent ducts is different to the separation between one or more other pairs of adjacent ducts. In an alternative embodiment, the ducts are disposed symmetrically with respect to the main axis (10).
(FR) La présente invention concerne un silencieux (1), qui comprend une entrée (3) de fluide et une sortie (4) de fluide disposée le long d'un axe principal (10), ainsi qu'une pluralité de conduits (6, 7, 12, 13, 14) de transmission de fluide qui s'étendent entre l'entrée (3) de fluide et la sortie (4) de fluide. Les conduits sont entourés d'un matériau (9) insonorisant et disposés à des positions respectives par rapport à l'axe principal (10), moyennant quoi la séparation entre au moins une paire de conduits adjacents est différente de la séparation entre une ou plusieurs autres paires de conduits adjacents. Dans un autre mode de réalisation, les conduits sont disposés symétriques par rapport à l'axe principal (10).
