Abstract
The thermal shrinkage of a casing () to regulate as best as possible the internal play between the rotor and the stator is carried out by a ring () fixed onto the skin () rather than by a circular ramp at a distance therefrom. The ring () comprises, between a collection box () and the skin (), a foraminous plate (), placed on an opening of the box () parallel to the skin () and at a short distance, in order to impose invariable and known ventilation conditions.
