A turbomachine assembly 1 comprising first and second bodies 2,3, at least one of which is rotating relative to the other, between which a tight zone EH is formed comprising a sealing gasket 16, a flowing fluid H, in particular lubricant oil, being able to circulate inside the bodies and to be driven toward said at least one rotating body from the other body, characterized in that said at least one rotating body comprises means for guiding the rotation, in the direction of rotation F3 of said at least one rotating body, of the flow of fluid away from the tight zone. Preferably the first and second bodies are casings of first and second contrarotating open rotors. The guiding means may comprise helical or longitudinal fins extending inside the at least one rotating body. The assembly prevents the flowing fluid from flowing towards the tight zone and leaking in to the working fluid flow and lubricant imbalances between the rotating bodies. |
