Abstract (en)

[origin: EP1445421A1] The device has a coolant circuit allowing cooling air to flow via openings in an upstream support (66) of an upstream disc. The air circulates downstream between an interior boring (48) of the disc and an upstream flange (78) of a downstream disc. A labyrinth (80) placed between the two discs separates the air flow into two (F1, F2), to circulate on both sides of the labyrinth in the direction of paddles (4, 6).
