Zusammenfassung:PROBLEM TO BE SOLVED: To restrict the variation of static pressure around the axis of a turbomachine while maintaining constant a performance for bleeding air from a high-pressure compressor. SOLUTION: This turbomachine compressor such as a high-pressure compressor comprises an air bleed means having a duct with a suction end communicating with the outer casing of the compressor at the same height as a rotor wheel and the stator stage of the compressor. A screen sheet of annular shape is mounted radially inside the casing facing a portion of the suction end of the duct so as to make the bleeding of air uniform over 360° around the axis of the compressor.
