A turbomachine subassembly including an annular gas flow path is delimited by a radially inner shell and a radially outer shell, a radial arm between the inner shell and the outer shell, that delimits an isolated volume of the annular flow path, which is connected to the inner volume in which a segment of a conduit, and ventilation air supply to a chamber delimited at least partly by the inner shell, through one radial arm, wherein the volume delimited by the radial arm is connected to the inner volume of the chamber and to a ventilation air supply source, wherein the external radial end of the arm supports a first connection box that closes off the external radial end of the arm, that includes a device for connecting the segment to the remainder of the conduit and a device for connecting the internal volume of the arm to the ventilation air supply source. |
