Abstract
The invention relates to a trunnion () for a high-pressure turbine (), to be arranged between a shaft of a low-pressure turbine () and an inner surface () of a seal mounting () of the low-pressure turbine (), the trunnion () being characterized in that it includes a drop-launching extension () arranged such as to extend opposite a flared portion () of the inner surface () of the seal mounting (), such that when the trunnion () is rotated about the shaft of the low-pressure turbine (), oil (H), which tends to penetrate between the trunnion () and the seal mounting (), is thrown by centrifugal effect from the drop-launching extension () toward the flared portion () of the inner surface () of the seal mounting ().
