Abstract

L'invention concerne un ensemble pour une turbomachine comportant un premier élément et un deuxième élément ayant un mouvement relatif de rotation l'un par rapport à l'autre autour d'un axe X, le premier élément et le deuxième élément étant chacun un élément différent pris parmi un élément de rotor et un élément de stator, le premier élément comportant une partie radialement interne (28) et une partie radialement externe (27), disposés radialement de part et d'autre d'une partie radialement médiane (20) du deuxième élément, ladite partie médiane (20) étant située axialement en regard de la première partie (27) et de la deuxième partie (28) du premier élément, le premier élément et/ou le deuxième élément comportant des léchettes (21a) qui s'étendent radialement entre la partie médiane (20) et la première partie radialement interne (28), d'une part, et des léchettes (21b) qui s'étendent radialement entre la partie médiane (20) et la deuxième partie (27), d'autre part, de manière à former des joints d'étanchéité entre lesdites parties (20, 27, 28).
