Title (EN) MULTI-CHAMBER HELMHOLTZ RESONATOR
(FR) RÉSONATEUR DE HELMHOLTZ À CHAMBRES MULTIPLES
Abstract:
(EN) A Helmholtz resonator (26) adapted to attenuate pressure fluctuations propagating in an injection fuel equipment, the Helmholtz resonator comprising at least one partition wall (38) dividing an inner space in distinct chambers (C1, C2), said partition wall being provided with an aperture (42) creating an internal fluid communication between said distinct chambers, the opening of the resonator opening in one of the chambers.
(FR) L'invention concerne un résonateur de Helmholtz (26) conçu pour atténuer des fluctuations de pression se propageant dans un équipement à carburant pour injection, le résonateur de Helmholtz comprenant au moins une paroi de séparation (38) divisant un espace interne en chambres distinctes (C1, C2), ladite paroi de séparation étant pourvue d'une ouverture (42) créant une communication de fluide interne entre lesdites chambres distinctes, l'ouverture du résonateur débouchant dans l'une des chambres.
