PROBLEM TO BE SOLVED: To form a sufficient supply section for air intake by a new injection device capable of enlarging the diameter of a swirler than a diameter corresponding to the contact surface between a defector and a bowl. SOLUTION: The invention relates to a novel device for injecting a mixture of air and fuel into a combustion chamber of a turbine engine. The injection device comprises radial swirlers 42 and 43 of outside diameter D2 having symmetry of revolution about an axis 33, a bowl 30 spaced axially from the radial swirlers 42 and 43, and a support ring 50 for supporting the injection device, which is arranged around the bowl. The bowl has a cylindrical wall 32 extended by a flared wall 31. In this novel device, the support ring 50 comprises a first cylindrical portion 51 of outside diameter D3 and a second cylindrical portion 52 of outside diameter D4 to which the first cylindrical portion is connected, the first cylindrical portion being connected to the cylindrical wall of the bowl by a plurality of support tabs 55.
