Zusammenfassung:	The turbine housing (10) features a circumferential wall (22) which coaxially surrounds a ring (30) surrounding the mobile blades (32) of the turbine. It includes a plurality of perforations (12) which brings air in to evenly ventilate the external face (22 e) of the circumferential wall (22). Le carter (10) de turbine comporte une paroi circonférentielle (22) qui entoure coaxialement un anneau (30) entourant les aubes mobiles (32) de la turbine. Il comporte une pluralité de perforations (12) qui apportent de l'air pour ventiler de façon homogène la face externe (22 e) de la paroi circonférentielle (22).
