Title: AIR AND FUEL INJECTION DEVICE FOR A TURBOMACHINE COMBUSTION CHAMBER
Abstract:
The invention relates to an air and fuel injection device (2) for a combustion chamber of a turbomachine comprising a fuel injector, at least a first element (21) mounted on the fuel injector and at least a second element (27, 28) mounted on an end wall (6) of the combustion chamber (1). The first element comprises a radial rim (25) able to move in a radial groove (26) of the second element (27, 28), which groove is delimited by a sleeve (27) and by a blanking ring (28) welded to the inside of the sleeve (27). The blanking ring (28) comprises a radial wall (34) and a cylindrical rim (35) extending from the radially external periphery of the radial wall (34) toward a radial wall (29) of the sleeve (27) and resting via its corresponding free end (39) against the radial wall (29) of the sleeve (27).
