An assembly for a combustion chamber of a turbomachine. The assembly comprises an annular shell extending along a longitudinal axis, the shell having an inner wall intended to be turned towards a furnace of the combustion chamber and an outer wall opposite the inner wall and a projecting element extending radially from an area of the outer wall. The shell has at least one deflector projecting from the outer wall and located downstream of the projecting element with respect to a direction of gas flow along the outer wall, oriented along the longitudinal axis. The deflector extends circumferentially. Perforations are provided axially between the projecting element and the or each deflector.

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.
