Abstract

A combustion chamber (15) comprises an upstream end wall (44), at least one fuel injector (56) and at least one seal (58). Each fuel injector (56) is arranged in a corresponding aperture (54) in the wall (44). Each seal (58) is arranged in a one of the apertures (54) in the wall (44) and around one of the fuel injectors (56). Each seal (58) has a first portion (60), a second portion (62) and a third portion (64). The second portion (62) abuts the corresponding fuel injector (56). The third portion (64) is arranged at the downstream end of the seal (58) and increases in diameter in a downstream direction. The first portion (60) is arranged upstream of the second portion (62) and has a plurality of coolant apertures (68) extending there-through. The coolant apertures (68) extend through the first portion (60) with axial, radial and tangential components. The seals (58) produce better mixing between the coolant and the fuel and air mixture from the fuel injectors (56) to reduce emissions produced in the combustion chamber.
