Abstract
A turbomachine assembly including first and second bodies, in which one of the bodies is rotating relative to the other body around the axis of rotation of the turbomachine, is provided. A tight zone is formed between the bodies and includes a sealing gasket. A flowing fluid, in particular lubricant oil, is able to circulate inside the first and second bodies and to be driven toward the one rotating body from the other body. The one rotating body includes a device for guiding the rotation, in the direction of rotation of the one rotating body, of the flow of fluid inside the one rotating body so as to drive the flowing fluid away from the tight zone.
