Claims (5)
- REVENDICATIONS1. Compresseur pour turbomachine comprenant un carter (4), au moins un étage de compresseur constitué d'une roue d'aubes fixes (2) et d'une roue d'aubes mobiles (1) positionnée en aval de ladite roue d'aubes fixes (2), et des cavités (5) creusées, de façon non communicantes entre elles, dans l'épaisseur dudit carter à partir de sa face interne et disposées parallèlement les unes aux autres sur une circonférence dudit carter (4) en regard du chemin de passage des aubes mobiles (1), lesdites cavités ayant une forme allongée selon une direction principale d'orientation et se refermant respectivement vers l'amont et vers l'aval par une face amont et par une face aval dont les intersections avec le carter forment respectivement une frontière amont (7) et une frontière aval (6), lesdites cavités étant décalées par rapport aux aubes mobiles (1) de façon à déborder vers l'amont de la roue d'aubes mobiles en recouvrant leur extrémité amont, caractérisé en ce que la frontière aval (6) de ces cavités (5) est orientée parallèlement à la corde en tête de l'aube mobile (1).
- 2. Compresseur selon la revendication 1 dans lequel la direction d'orientation desdites cavités est perpendiculaire à celle de la corde en tête des aubes mobiles (1).
- 3. Compresseur selon l'une des revendications 1 à 2 dans lequel les cavités (5) sont réparties de façon régulière sur la circonférence du carter (4).
- 4. Compresseur selon l'une des revendications 1 à 2 dans lequel les cavités (5) sont réparties de façon non régulière sur la circonférence du carter (4).
- 5. Turbomachine comportant un compresseur selon l'une des revendications précédentes.
