Abstract (en)
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.
Abstract (fr)
Refroidissement d'une partie du dispositif d'injection correspondant à un circuit secondaire par une circulation de carburant à débit permanent d'un circuit primaire. Le circuit secondaire (19) est connecté à une chambre de distribution (30) percée d'une pluralité de trous d'éjection de carburant et le circuit primaire (17) comporte au moins une partie de conduit (86) jouxtant la chambre de distribution, pour son refroidissement.
