Abstract

L'invention concerne un carter (1) de turbomachine, comprenant : - une cavité (2) dans laquelle circule de l'air sous pression en rotation dans ladite cavité, et - au moins une bouche (3) de prélèvement reliée à un tube (4) de prélèvement, pour le prélèvement de l'air hors de la cavité (2), caractérisé en ce que le carter (1) comprend au moins un dispositif (5) de guidage de l'air, o comprenant une portion (7) qui s'étend en saillie dans la cavité (2), à partir et dans le prolongement de la bouche (3) de prélèvement, o fixe par rapport au carter (2), et o étant configuré pour guider l'air en rotation dans la cavité (2) à partir de ladite cavité (2) vers le tube (4) de prélèvement, à travers ladite bouche (3) de prélèvement. L'invention concerne également une turbomachine comprenant un compresseur, et ledit carter, pour le prélèvement d'air comprimé à partir du compresseur.
