Abstract (en)

[origin: EP1640662A1] The injector (2) has a tubular gas duct (16) arranged inside the fuel duct (6), with several orifices (18) opening out into fuel duct, to inject gas at a pressure greater than predetermined pressure and equal to pressure threshold so as to create effervescence in the fuel on being introduced into the main structure (4). The orifices of the gas duct are arranged in at least one of the common transverse plane. Independent claims are also included for the following: (1) aeromechanical injection system; and (2) turbo machine.
