Abstract: This machine comprises two volute casings describing an orbital relative movement, one of the volute casings being fitted with at least one scroll (7) and the other volute casing being equipped with at least two scrolls (12, 13), the various scrolls delimiting a first series of variable-volume chambers (18a-18d) belonging to a first compression or expansion stage, and a second series of variable-volume chambers (18e-18h) belonging to a second compression or expansion stage, each stage comprising a high-pressure fluid passage (24, 28) designed to open into one of the chambers of the respective stage and a low-pressure fluid passage (19a, 19b, 26) designed to open into one of the chambers of the respective stage. The portion of the low-pressure fluid passage (26) of the second stage that is designed to open into one of the chambers of the second stage is further away from the zone of convergence of the scrolls delimiting the variable-volume chambers of the second stage than the portion of the high-pressure fluid passage (24) of the first stage that is designed to open into one of the chambers of the first stage.
