Title (EN) TURBOCHARGER HAVING VARIABLE COMPRESSOR TRIM
(FR) TURBOCOMPRESSEUR À TRIM DE COMPRESSEUR VARIABLE
Abstract:
(EN) A turbocharger includes a compressor and an airflow adjustment assembly. The airflow adjustment assembly includes a plurality of guide vanes. Each of the plurality of guide vanes has a guide tip and a guide base spaced from the guide tip along an axis. The guide tips define a vane diameter (VD) less than the inlet diameter (ID) and perpendicular to the axis. The airflow adjustment assembly further includes a sliding ring and a plurality of connecting rods. The sliding ring is configured to be axially movable along the axis. Additionally, the plurality of connecting rods are axially moveable along the axis when the sliding ring moves axially along the axis, thereby selectively increasing and/or decreasing the vane diameter (VD) when the sliding ring moves axially along the axis.
(FR) L'invention concerne un turbocompresseur comprenant un compresseur et un ensemble de réglage de flux d'air. L'ensemble de réglage de flux d'air comprend une pluralité d'aubes de guidage. Chaque aube de la pluralité d'aubes de guidage a une pointe de guidage espacée d'une base de guidage le long d'un axe. Les pointes de guidage définissent un diamètre d'aube (VD) inférieur au diamètre d'entrée (ID) et perpendiculaire à l'axe. L'ensemble de réglage de flux d'air comprend en outre un anneau coulissant et une pluralité de tiges de liaison. L'anneau coulissant est conçu pour être axialement mobile le long de l'axe. De plus, la pluralité de tiges de liaison sont mobiles axialement le long de l'axe lorsque l'anneau coulissant se déplace axialement le long de l'axe, ce qui augmente et/ou diminue sélectivement le diamètre d'aube (VD).
