ABSTRACT:
A system for ventilating a combustion chamber wall in a turbomachine is disclosed. The system includes a diffuser mounted at the inlet of the combustion chamber, an annular end-piece that extends downstream to an injection device for injecting ventilation air, and an annular convecting metal sheet being arranged radially between the combustion chamber and the end-piece of the diffuser in order to delimit, with an internal wall of the chamber, an annular stream for the flow of air that is stable and without separation supplying holes in the chamber and the injection device.
