Abstract

L'invention concerne le refroidissement d'une nervure d'étanchéité (36a, 36b) d'un joint tournant (30) assurant l'étanchéité entre un arbre de rotor (18) et un redresseur (24) dans un compresseur axial (10) de turbomachine. L'invention propose à cet effet des moyens de canalisation d'air (48) aptes à prélever de l'air de refroidissement en aval du redresseur (24) et capables d'injecter cet air de refroidissement de sorte que ce dernier baigne un flanc de la nervure d'étanchéité.The invention relates to cooling a sealing rib (36a, 36b) of a rotary joint (30) sealing between a rotor shaft (18) and a stator (24) in an axial compressor (10). ) turbomachine. The invention provides for this purpose air ducting means (48) capable of taking cooling air downstream of the rectifier (24) and capable of injecting this cooling air so that the latter bathes a sidewall. of the sealing rib.
