CA 2442749

The invention relates to a rotor gap control module (6) for a turbine machine with a rotor (5) and a housing, which surrounds the rotor, forming a rotor gap (S). The rotor gap control module is provided with an actuator, acting on a seal element (8) and displacing the same into or out of the rotor gap. In order to increase the response behaviour the seal element is smaller than the gap between two sequential rotor blades.

L'invention concerne un module de commande (6) du jeu de rotor destiné à une turbomachine, qui comprend un rotor (5) et un carter entourant le rotor en formant un jeu (S). Ce module de commande de jeu est équipé d'une unité d'actionnement, agissant sur un élément d'étanchéité (8) en l'animant d'un mouvement de va-et-vient à l'intérieur du jeu. L'objectif de cette invention est d'accélérer le temps de réponse. A cet effet, cet élément d'étanchéité présente une dimension inférieure à la distance entre deux aubes successives du rotor.
