Abstract (en)

[origin: EP1806536A1] The multi-mode injector, containing two coaxial fuel atomising systems fed by primary (17) and secondary (19) circuits, has an atomising head in which the secondary circuit is connected to an annular distribution chamber (30) pierced with a series of equally-spaced fuel ejection holes (31). In the head the primary circuit forms at least part of a cooling duct (86) adjoining the distribution chamber and made with inner and outer radial surfaces.
