Abstract
(EN)
A compressor portion (30) has a diffuser chamber (54), a scroll chamber (56) and a diffuser vane unit (38). The diffuser vane unit (38) is made up of a single vane, and is disposed so that the angle θ that represents the front end position thereof to the impeller-housing chamber (52) side is in the range of 0°≤θ≤180°.
(FR)
L'invention porte sur un compresseur dont une partie (30) possède une chambre formant diffuseur (54), une chambre formant volute (56) et une unité volet de diffuseur (38). L'unité volet de diffuseur (38) est composée d'un seul volet et elle est disposée de telle sorte que l'angle θ qui représente sa position extrême avant sur le côté de la chambre (52) de logement de la roue mobile est compris dans l'intervalle de 0°≤θ≤180°.
