be located near split ring 23 for example liner 31 is a cylindrical sleeve that extends axially along the inner circumference 27 toward exhaust system 15 continuing with fig2 in the drawings exhaust system 15 has an outer liner 33 and an inner liner 35 an adapter can 37 attaches to heat shield 19 and abuts outer liner 33 an aft seal ring 39 is attached to inner liner 35 aft seal ring 39 has a preferably circumferential axial face 41 referring now to fig3 a corrugated bellows 43 is positioned between axial face 41 of aft seal ring 39 and axial face 29 of split ring 23 bellows 43 is preferably a free floating circumferential unit though one end of bellows 43 may be fixedly attached relative to engine 13 or to exhaust system 15 a lip 45 is formed on each axial ends of bellows 43 with lips 45 being formed to be parallel to axial faces 29 39 bellows 43 is compressed slightly between axial faces 29 41 to provide axial pressure between each lip 45 and the corresponding axial face 29 41 lips 45 and axial faces 29 41 cooperate to form face seals for preventing the escape of exhaust gases at the junction of engine 13 and exhaust system 15 continuing with fig3 a close up sectiorial view of bellows 43 shows how it relates to the nearby parts bellows 43 has corrugations 47 between lips 45 that may be compressed axially and.
