Abstract (en)

The injector comprises a channel (31) through which a liquid fuel forming a film lining on its wall and a spraying fluid are transmitted. The fuel is then projected in a mist with the spraying fluid. From the channel to the injector free end is a film destabilization chamber (32) with a transverse section greater than that of the channel. A film extracting constriction (33) extending from the destabilization chamber has a transverse section less than that of the chamber. An Independent claim is included for a burner using the injector.
