| description | A single-shaft exhaust gas-driven turbocharger includes two parallel-flow first-stage centrifugal compressors in series with a single second-stage centrifugal compressor, and a one-stage turbine arranged to drive both the first- and second-stage centrifugal compressors via a single shaft on which the compressors and turbine are fixedly mounted. The compressor housing defines from one to a plurality of circumferentially spaced inlet ducts for the second wheel of the first stage, and from one to a plurality of circumferentially spaced interstage ducts leading from a vaneless diffuser of the first stage into the inlet of the second stage.
L'invention porte sur un turbocompresseur entraîné par un gaz d'échappement à arbre unique, lequel turbocompresseur comprend deux compresseurs centrifuges de premier étage à écoulement parallèle en série avec un unique compresseur centrifuge de second étage, et une turbine à un étage agencée pour entraîner à la fois les compresseurs centrifuges de premier et de second étages par l'intermédiaire d'un unique arbre sur lequel les compresseurs et la turbine sont montés de manière fixe. Le boîtier de compresseur est défini à partir d'une à une pluralité de conduites d'entrée espacées circonférentiellement pour la seconde roue du premier étage, et à partir d'une à une pluralité de conduites entre étages espacées circonférentiellement menant à partir d'un diffuseur sans aubes du premier étage dans l'entrée du second étage. |
