Abstract:
Fuel injector for an oil burner, internally comprising a duct through which a fuel in the liquid state at least partially in the form of a film lining the internal wall of the duct and an atomizing fluid is introduced into said duct of the fuel injector and are transmitted to the downstream part of the injector which terminates at the free end thereof through which the fuel is sprayed from the injector forming a mist with the stream of atomizing fluid, wherein the this downstream part has internally, in longitudinal alignment with the duct, and in succession towards the free end, a chamber for destabilizing the film which has a cross section that is larger than that of the duct, a throat for detaching the film extending the destabilization chamber and having a cross section that is smaller than that of the chamber, and a spray orifice which is open at the free end of the injector, into which the detachment throat opens, and which has a cross section that is larger than that of the throat.
