Abstract
A fuel injector in which, an annular intermediate flow containing fuel is ndwiched between an inner and an outer flow of air caused to rotate by swirl-promoting bladed devices called 'swirlers,' the inner flow being generated in a tubular duct which is closed at its upstream end with a bottom plate, and the 'swirler' associated with said inner flow being a centripetal bladed device that opens to the tubular duct upstream of an annular duct supplied with fuel and itself opening at its downstream end to the tubular duct, thus forming a sharp enlargement within the tubular duct.
