Beschreibung
Zusammenfassung:	A combustion chamber includes an upstream end wall having an aperture and a fuel injector. An air swirler (48) is mounted radially movable with respect to the aperture. An inner wall (50) of the air swirler (48) has a first portion (70). A fuel injector head of the fuel injector is arranged coaxially within the air swirler (48). An outer wall (66) of the fuel injector head has a first portion (68). The inner diameter of the first portion (70) of the air swirler (48) is less than the outer diameter of the first portion (68) of the fuel injector head. One of the first portions (70, 68) is elastically radially deformable to allow the fuel injector head to be installed and removed from the air swirler (48). The inner wall (50) and the outer wall (66) have inter-engaging radially and axially extending faces (82, 88A & 88B) to align the fuel injector head axially and radially within the air swirler (48) when inserting it in the direction (I).
