The rotor disk (3B) for a compressor comprises, relative to the rotational axis of the disk: a radial web (4), blades (8) at the outer periphery of the web, a bore (5) at the inner periphery of the web, and a cylindrical side wall (12) extending the web in the vicinity of the outer periphery of same and having an air supply port (18), and—a centripetal air collection device (15). Advantageously, the device (15) comprises a cylindrical support (23) and at least one air supply tube (16), the inlet of which is turned towards the port (18) and the outlet of which is turned towards the bore (5) in the web, the disk comprising an inner radial flange (40) extending from the cylindrical side wall (12), the cylindrical support (23) of the device (15) being attached to said inner radial flange (40), and a ring (30) extending from the web (4), the cylindrical support (23) being centred on the ring (30). |
