摘要:
The invention concerns a device for protecting against oil leaks towards the rotors of a turbomachine turbine (2), comprising an upstream cavity (18) in which an oil/air mixture can circulate, said upstream cavity being delimited downstream by a journal (8) of the turbine rotor and on the outside by a sealing flange (14) of the journal extending axially in an upstream direction, a downstream cavity (20) opening towards the discs (12) of the turbine and communicating with the upstream cavity via a plurality of ventilation holes (22) provided in the journal, and an upstream annular deflector (24) fixed to the sealing flange of the journal and extending radially inwards towards the ventilation holes, the upstream deflector having oil passage ports (26) provided at the end of same secured to the sealing flange of the journal.
