Abstract
Vanne de décharge (30) pour turbomachine (10), comportant un boîtier fixe (31) définissant un conduit interne et relié à une entrée d’air et à une sortie d’air, un organe mobile (34) entre au-moins deux positions, respectivement d’ouverture et de fermeture dudit conduit, un espace annulaire (44) audit boîtier (31), configuré pour être alimentée en gaz sous pression (42) en vue du déplacement dudit organe (34) entre ses deux positions. Ledit organe mobile (34) comprend une portion tubulaire qui délimite intérieurement un passage d’écoulement d’air (32) de décharge, et qui est entourée par ledit espace annulaire (44).
