Title (EN) DOUBLE FLOW TURBINE HOUSING TURBOCHARGER
(FR) TURBOCOMPRESSEUR COMPRENANT UNE TURBINE À DOUBLE FLUX
Abstract:
(EN) Implementations of the present disclosure are directed to turbine assemblies for turbocharger systems. In some implementations, turbine housings include a body that defines an inlet for fluid communication with a fluid source, and a wall, the wall dividing the inlet into an inner inlet and an outer inlet, and a fluid guide assembly disposed within the housing, the fluid guide assembly including a plurality of vanes that demarcate an inner volute and an outer volute within the housing, the inner volute being in fluid communication with the inner inlet and the outer volute being in fluid communication with the outer inlet, each vane of the plurality of vanes being fixed at a respective angle relative to a radial direction, the plurality of vanes guiding fluid flow from the outer volute to the inner volute.
(FR) La présente invention porte sur un turbocompresseur. Certaines modes de réalisation de la présente invention concernent des ensembles turbines pour systèmes de turbocompresseurs. Dans certaines modes de réalisation, des carters de turbines comprennent un corps qui définit une entrée pour la communication fluidique avec une source de fluide, et une paroi, la paroi divisant l'entrée en une entrée intérieure et une entrée extérieure, et un ensemble de guidage du fluide disposé dans le carter, l'ensemble de guidage du fluide comprenant une pluralité de volets qui délimitent une volute intérieure et une volute extérieure dans le carter, la volute intérieure étant en communication fluidique avec l'entrée intérieure et la volute extérieure étant en communication fluidique avec l'entrée extérieure, chaque volet de la pluralité de volets étant fixé à un angle respectif par rapport à une direction radiale, les différents volets guidant l'écoulement du fluide de la volute extérieure vers la volute intérieure.
