Combustion chamber and a combustion chamber fuel injector seal

A combustion chamber comprising an upstream end wall, at least one annular wall, at least one fuel injector and at least one seal,

• the at least one annular wall being secured to the upstream end wall,
• the upstream end wall having at least one aperture,
• each fuel injector being arranged in a corresponding one of the apertures in the upstream end wall,
• each seal being arranged in a corresponding one of the apertures in the upstream end wall and around the corresponding one of the fuel injectors, each seal having an inner surface facing the corresponding one of the fuel injectors and an outer surface facing away from the corresponding one of the fuel injectors, each seal abutting the corresponding one of the fuel injectors, the downstream end of each seal increasing in diameter in a downstream direction, the upstream end of each seal having a radially extending flange extending outward of the outer surface, the downstream end of each seal being positioned axially downstream of the upstream end wall, each seal being located in the corresponding one of the apertures in the upstream end wall such that an annular space is formed between the outer surface of the seal and the upstream end wall, each seal having a plurality of thermal conductors extending axially from the radially extending flange to the downstream end of the seal, and wherein each thermal conductor extends radially outwardly from the outer surface of the seal throughout the full axial distance between the radially extending flange and the downstream end of the seal.
