Abstract
L’invention concerne un circuit multipoint (M) d’injecteur de carburant, en particulier pour une turbomachine d’aéronef comportant une chambre de combustion (10), ledit circuit multipoint (M) comportant au moins un orifice d’injection (20) destiné à injecter du carburant dans la chambre de combustion (10), l’au moins un orifice d’injection (20) étant alimenté en carburant par des moyens (22) d’alimentation en carburant, caractérisé en ce que l’au moins un orifice d’injection (20) est alimenté en gaz par des moyens (24) d’alimentation en gaz de manière à réaliser un mélange gaz/carburant en amont de la chambre de combustion (10) et à injecter le mélange gaz/carburant dans la chambre (10). Figure pour l'abrégé : Figure 2The invention relates to a multipoint fuel injector circuit (M), in particular for an aircraft turbomachine comprising a combustion chamber (10), said multipoint circuit (M) comprising at least one injection orifice (20) intended to inject fuel into the combustion chamber (10), the at least one injection orifice (20) being supplied with fuel by fuel supply means (22), characterized in that the at least an injection orifice (20) is supplied with gas by gas supply means (24) so as to produce a gas/fuel mixture upstream of the combustion chamber (10) and to inject the gas/fuel mixture in the room (10).
