A COMBUSTION CHAMBER SEALING RING, AND A COMBUSTION CHAMBER INCLUDING SUCH A RING

摘要

The present invention provides a fixing or sealing ring (1) for maximizing cooling at the end of a combustion chamber wall. For this purpose, the ring (1) is constituted by a sleeve (1a) which is fixed around the end of a wall (51a) of the combustion chamber by means of a plurality of orifices for receiving fasteners or by means of any other system for connecting the ring to the wall. The sleeve (1a) includes at least one recess (3) in its face facing the wall (51a) of the combustion chamber, thereby reducing the area of the sleeve (1a) that presses against the wall (51a), and co-operating with said wall to form an open cavity (6) in which a cooling air stream (63) can flow.
