FUEL INJECTOR

摘要

A fuel injector (2) including a combustion air flow conduit, a fuel inlet (2.4) and means to mix the air and fuel flowing therethrough (2.2, 2.3, 2.6), additionally comprising fluidic control means (2.7) including at least one control port (3.4, 3.5, 3.6, 3.7), such that flow of control air through said control port allows variation in the degree of flow resistance to which combustion air is subjected. For example, control air flowing through the control port may impart swirl to the combustion air flow from the inlet, thereby subjecting the combustion air flow to increased resistance. Alternatively a fluidic diverter (2.7) may selectively divert the main flow to either the first or second sub-conduits (2.2, 2.3), each sub-conduit subjecting combustion air to different degrees of flow resistance.
