摘要

The turbomachine has a rotor composed of disks (13, 15) that are assembled along a common axis and reunited by an annular connecting part (37). A sealing unit (39) is arranged between blades (21, 23) of each of the two disks and a crown of a diffuser blade (19) intercalated axially between the disks. The sealing unit has an annular trim (41) installed at inner radial part of the crown, and two annular supports linked to blades of the disks. Independent claims are also included for the following: (1) a turbine (2) a compressor.
