A turbomachine or high pressure compressor including a stator casing housing a plurality of compression stages that are spaced apart in an axial direction along the central axis of the turbomachine, each compression stage including a row of rotor blades followed by a row of stator vanes. The compressor further includes an air injection system including at least one air injection passage through the casing and including an outlet segment that opens out in an inclined manner upstream from and directed towards a row of rotor blades into a set-back zone of the inside face of the casing.

Turbomachine compressor with an air injection system

The present invention relates to an improvement in the clearancesbetween a casing and the moving bladesof a rotorof a turbomachine, in particular a casing provided for this purpose, and also to a turbomachine fitted with such a casing. The invention applies in particular to aircraft turbojet engines. It relates more particularly to a turbomachine inner casingcomprising a plurality of annular shroudsthat are provided with flangesfor joining two adjacent shroudstogether. According to the invention, this inner casingfurther includes:
