The invention relates to a turbomachine (1) with a rotor (25) that extends along a rotational axis (15). Said rotor (25) has a rotor shaft groove (31) with a groove base (33) and a rotor blade (13) with a blade footing (35). Said blade footing (35) is introduced into the rotor shaft groove (31) and a gap (37) is formed between the blade footing (35) and the groove base (33). A sealing element (39) is provided for sealing said gap (37). Said sealing element is at least partially accommodated by the blade footing (35) and is mobile in relation to the same. The invention also relates to a sealing element (39), especially for a rotor (25) of a turbomachine (1), comprising a first partial sealing element (53A) and a second partial sealing element (53B). The inventive sealing element (39) performs its sealing action under the influence of an external force, especially the centrifugal force.

Turbomachine (1) qui comporte un rotor (25) s'étendant le long d'un axe de rotation (15). Le rotor (25) possède une rainure (31) d'arbre de rotor présentant une surface de fond (33), ainsi qu'une aube (13) dotée d'une emplanture (35) d'aube. L'emplanture (35) est installée dans la rainure (31) d'arbre de rotor et un espace (37) est formé entre l'emplanture (35) d'aube et la surface (33) de fond de la rainure. Un élément d'étanchéité (39) qui est logé au moins en partie dans l'emplanture (35) et qui est mobile par rapport à cette dernière sert à étanchéifier l'espace (37). La présente invention concerne en outre un élément d'étanchéité (39), en particulier pour un rotor (25) de turbomachine (1), qui possède des premier (53A) et second (53B) élements partiels d'étanchéité. L'élément d'étanchéité (39) déploie sont effet d'étanchéité sous l'effet d'une force externe, en particuler la force centrifuge.
