TURBOJET VENTING PIPE, METHOD FOR MOUNTING ONE SUCH PIPE AND TURBOJET PROVIDED WITH ONE SUCH PIPE

摘要

The invention relates to a venting pipe used to guide a gas stream in a turbojet comprising at least one hollow rotary shaft (2) inside which the pipe is mounted, said pipe extending generally along an axis A. The pipe is characterised in that it comprises at least two pipe segments (8a, 8b) intended to be aligned longitudinally and assembled to one another while retaining a degree of freedom in the relative translation thereof, at least one of said segments (8b) being provided with deformable means (16) configured to deform radially as the pipe segments (8a, 8b) are ¨tightened against one another in the shaft (2) of the turbojet (1), in order to bear on the shaft (2). The invention facilitates the mounting of the venting pipe.
