Abstract

1. A device for distributing cooling gas under a retaining sleeve (3) at one end of the excitation winding of a turbo- alternator rotor, comprising a cylinder of electrically insulating material (6) disposed immediately under the end of the winding, provided with gas admission windows (7) between the coils of this winding, as well as radial (8) and circumferential partitions (9) disposed between the cylinder of insulating material and the rotor shaft (1) and dividing the annular orifice between the cylinder of insulating material and the shaft into radial compartments for cold gas inlet (10) and for hot gas outlet (11), both being connected to inlet and outlet channels disposed between the ends of the coils, characterized that the gas admission and exhaust channels are themselves connected to channels inside the conductors via side openings of the latters, and that the exhaust channels are connected to a single outlet compartment in the center of each pole.
