    摘要: The invention relates to a device for injecting an air/fuel mixture into a combustion chamber, which is to be mounted within a restricted space. This injection device (20) comprises a bowl (70) having an external cylindrical wall (73) continued at its downstream end by a divergent section (74) provided, downstream, with a collar (75) having the form of a ring extending radially outward, the divergent section of the bowl being connected, immediately upstream of the flange, by a connecting wall (76) to a cylindrical ring (77), the cylindrical ring and the connecting wall forming a connection rim oriented in the upstream direction. At least one row of vortex holes (79) is formed in the external cylindrical wall, close to its upstream end, and the connecting wall of the connection rim of the bowl is provided with a row of cooling orifices (81) inclined axially at an angle y to the axis of symmetry of the injection device.
