A rotary bleed valve (10) for a gas turbine engine comprises a passage (11) connecting high pressure gases from a compressor to an exhaust and a valve member (12). the valve member (12) may be rotated within the passage (11) so as to vary or if necessary block the flow of compressor gases. The valve member (12) is shaped such that as the member (12) moves from a closed to an open position gas flows around the member (12) induces a torque on the member (12).
L'invention concerne un ensemble soupape de purge (10) rotatif destiné à un moteur de turbine à gaz comprenant un passage (11) qui évacue des gaz à pression élevée provenant d'un compresseur vers un échappement, et un élément de soupape (12). Ledit élément de soupape (12) peut tourner dans le passage (11) de façon à faire varier ou à bloquer, le cas échéant, l'écoulement des gaz du compresseur. Cet élément (12) est mis en forme de sorte qu'il se déplace d'une position fermée vers une position ouverte, le gaz s'écoulant autour dudit élément (12) induisant un couple sur cet élément (12).
