ABSTRACT:
System for cooling a downstream cavity of a centrifugal compressor impeller in a turbomachine, this compressor being connected to a diffuser comprising a downstream annular flange, an annular plating being mounted coaxially around the flange of the diffuser and substantially extending over the entire axial dimension of the flange so as to define an annular ventilation passage fed with air which is cooler than the air exiting the centrifugal compressor.
