Abstract (en)
[origin: EP2071241A1] The device has a ring (150) and a bush (152) mounted coaxially one inside the other. The bush is fixed on an edge of an orifice of an external wall of a combustion chamber. The bush has annular parts i.e. annular piece (164) and a square shaped washer (166) fixed one on another by brazing or welding, where the parts define an annular groove. The ring is moved in a transverse direction. The annular parts are fixed together via welding or brazing zones (180), where the zones are outside a trajectory of edge of the ring when the zones are placed relative to the bush in the direction.
