Abstract (en)

A turbocharger centrifugal compressor has a volute (12) which overlaps itself and a divider neck or tongue (40) which divides flow from the impeller (26) into upstream and downstream parts of the volute where it overlaps itself, and in order to reduce noise the neck extends to a region adjacent the outlet of the impeller, whether by being connected to the outlet end of a diffuser blade (34A) where there is a vaned diffuser between the impeller and volute or by connection across the diffuser (42) it the diffuser is a vaneless diffuser.
