Beschreibung
Zusammenfassung:	The invention relates to a turbojet section comprising an external casing having a surface that extends radially inwards, an internal casing having an essentially axial wall that extends toward said surface, and a seal located between said wall and said surface to prevent communication between the high and low pressure regions situated on either side of said seal, in which said seal is made in the form of an annular sheet-metal ring comprising an essentially cylindrical first part fixed in a leaktight manner to one face of the axial wall and a second part continuing from said first part and situated in the space separating said axial wall from said radial surface, said second part exhibiting, in section on a radial plane containing the axis of the turbojet, a V-shaped profile and having an end portion in leaktight sliding contact with said radial surface.
