Abstract (en)
[origin: EP0828115A1] A fuel/air injector consists of an axial fuel injector (2), a coaxial Venturi tube (6) forming a pre-mix chamber (3), a divergent outlet (8) with a ring (9) for fixing to the tube (6), and an atomising air inlet. The atomising air inlet is equipped with a radial swirler (10) with a high level of permeability, situated in front of the Venturi tube (6) and providing a primary fuel/air mix. A second radial swirler with a series of channels (16a, 16b) is situated round the forward end of the tube with outlets in its convergent section to ensure a homogenous carburation of the fuel inside the tube. A third swirler (18a, 18b) is located round the rear end of the tube and has axial outlets which alternate in a circumferential direction with the radial outlets of the second swirler.
