Beschreibung
Zusammenfassung:	The invention relates to a turbomachine element comprising a stator (2), a rotor (1), and a first sealing means (9) for sealing between the rotor (1) and the stator (2) arranged to be active when the rotor is in the operating position of same around the axis of rotation (LL) thereof, the element being characterized in that it comprises an auxiliary pressure sealing means (20, 22), sealing between the rotor (1) and the stator (2), and is arranged so that the two sealing means are active when the rotor (1) is placed along the axis of rotation (LL) thereof during an assembly operation in a test position, the rotor (1) and the stator (2) forming, in said test position, an enclosure (8) between said two sealing means. L'invention concerne un élément de turbomachine comprenant un stator (2), un rotor (1), et un premier moyen d'étanchéité (9) entre le rotor (1) et le stator (2) agencé pour être actif lorsque le rotor est dans sa position de fonctionnement autour de son axe de rotation (LL), élément caractérisé en ce qu'il comprend un moyen d'étanchéité auxiliaire (20, 22) en pression, entre le rotor (1) et le stator(2), et qu'il est agencé pour 10 que les deux moyens d'étanchéité soient actifs lorsque le rotor (1) est placé le long de son axe de rotation (LL) lors d'une opération de montage dans une position de test, le rotor (1) et le stator(2) formant, dans cette position de test, une enceinte (8) entre lesdits deux moyens d'étanchéité.
