<p><P>PROBLEM TO BE SOLVED: To solve problems of a mounting tube for pressurizing an internal casing in a turbomachine by a simple, effective, and inexpensive method. <P>SOLUTION: This turbomachine includes high-and low-pressure compressor shafts guided into bearings isolated from an internal casing by a sealing end plate, and radial pressurization tubes connecting the casing to an air passage extending through an intermediate casing. The ends of these tubes are engaged in sealed manner in radial ducts of the intermediate casing and in radial chimneys of a sealing end plate. The chimney has a length sufficient for the ends of the tubes to move in translation therein between a service position and a mounting position for the tubes. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
