Abstract

Un carter inter-compresseur (40) pour turbomachine comprend une virole (54) délimitant extérieurement un tronçon de veine annulaire (PV), et un système de décharge d’air comprenant des orifices (60) formés dans la virole pour raccorder le tronçon de veine annulaire avec un passage d’évacuation d’air (61), et une porte VBV (62) montée pivotante selon un axe de pivotement (64) de manière à être déplaçable entre une position de fermeture, dans laquelle la porte VBV ferme un orifice (60), et une position d’ouverture, dans laquelle la porte VBV permet une circulation d’air au travers de l’orifice. L’axe de pivotement est agencé entre un bord amont (66) et un bord aval (68) de l’orifice à une distance des bords amont et aval telle que, dans la position d’ouverture, la porte VBV permet une circulation d’air au travers d’une portion amont (60A) de l’orifice et au travers d’une portion aval (60B) de l’orifice.
