Abstract
Une vanne de commande de turbine à air dynamique comprend un manchon, un corps et un logement de retour. Le manchon définit un premier port de sortie disposé à proximité d'une première extrémité du manchon et définit un second port de sortie disposé entre le premier port de sortie et la première extrémité. Le corps est contenu radialement dans le manchon et est mobile entre une première position et une seconde position. Le logement de retour est couplé à la première extrémité du manchon et définit une cavité qui reçoit un élément de précontrainte qui entre en prise avec le corps.
