Beschreibung
Zusammenfassung:	A fuel swirler (12) has a swirler housing (16) defining an interior chamber (15) having a fuel outlet (18) at a downstream end (D.E). A swirler core (13) is mounted inside the interior chamber (15). The swirler core (13) has a downstream end portion (24) with one or more fuel channels (29) disposed thereon. The one or more fuel channels (29) is in fluid communication with the fuel outlet (18). An internal bore (14) extends longitudinally through the swirler core (13). The internal bore (14) has an inlet (23) connectable to a source of fuel. One or more exit holes (28) fluidly connects the internal bore (14) to the one or more fuel channels (29). An annular air gap (22) is provided radially between the swirler housing (16) and the swirler core (13) for thermally shielding the internal bore (14).
