An air-assisted single jet injector.

摘要

An air-assisted single jet injector (1) in which a valve shutter (11) actuated by an electromagnetic actuator (7) controls the formation of jets of fuel through atomisation orifices (15) formed in a delivery element (5) downstream of which an auxiliary atomisation chamber (21) is arranged, defined internally at least in part by a frusto-conical surface (24b) into which open radial holes (25) for the induction of an auxiliary air flow having respective axes perpendicular to the surface (24b).
