摘要：
A diffuser-nozzle assembly mounted at the outlet from a centrifugal compressor is disclosed. The assembly includes a plurality of vanes carried by a radially inner wall forming a surface of revolution and surrounded by an outer casing, elastically deformable devices interposed between the radially outer ends of the vanes of the nozzle and the outer casing. The elastically deformable devices prevent air from passing between the outer casing and the radially outer ends of the vanes.
