Patent ID: 8123465

Claim:
A turbomachine compressor module comprising: a low-pressure compressor and a high-pressure compressor having shafts that are guided in bearings that are isolated from an internal enclosure containing the compressor shafts by labyrinth seals mounted on a sealing end plate carried by an intermediate casing; and radial tubes for pressurizing the internal enclosure, connecting said enclosure to a compressed air passage passing through the intermediate casing, the ends of these radial tubes being engaged in sealed manner in radial ducts of the intermediate casing and in radial chimneys of the sealing end plate, means being provided to hold the ends of the radial tubes stationary in the radial ducts of the intermediate casing, wherein the radial chimneys of the sealing end plate are of radial size or length that is sufficient to enable the radially inner ends of the radial tubes to be moved therein in translation between a service position in which the radially outer ends of the radial tubes are mounted in sealed manner in the radial ducts of the intermediate casing, and a mounting position in which the radially outer ends of the radial tubes are not in the radial ducts of the intermediate casing.
