The chamber has a separator (70) arranged between an internal annular ferrule (151) and an internal slit (21). The separator has a tubular part (76) dividing a downstream annular chute (40) into an internal annular chute (82) and an external annular chute (81) such that air flow running along the ferrule is divided into an internal air flow (Fi) and an external air flow (Fe). The chute is formed between the ferrule and the slit. The internal air flow passes between the tubular part and the slit, and the external air flow passes between the ferrule and the tubular part. |
