Brush seal for sealing two spaces of differing pressure between a stator and a rotor of a turbomachine. The bristles of the brush seal comprise angled bristle sections, of which the ends run against the seal surface of the rotor. In this manner, a low bristle stiffness and a low required radial structural space can simultaneously be achieved.

Joint à brosse assurant l'étanchéité de deux chambres sous des pressions différentes (P1, P2) entre un stator (20) et un rotor (10) d'une turbomachine. Les soies (30) du joint à brosse présentent des sections coudées (31) dont les extrémités reposent sur la surface d'étanchéité du rotor (10); on obtient ainsi, à la fois, une faible rigidité des soies et un plus faible encombrement radial.
