Abstract
A fuel nozzle for a gas turbine engine includes a fuel tube enclosed by a housing. The fuel tube and housing are connected by a movable joint including a tubular seat formed on the housing and a boss formed on the fuel tube so as to be disposed within the tubular seat. The boss includes a contact surface that is in sliding engagement with the tubular seat and is rotatable about an axis that is perpendicular to the seat's longitudinal axis. The fuel nozzle further includes a fixed joint that connects the housing to the same section of the fuel tube as the movable joint.
Claims36
A fuel nozzle comprising:
- a fuel tube;
- a fuel tip attached to one end of said fuel tube;
- a housing disposed around said fuel tube so as to define an air gap therebetween;
- and
- a movable joint between said housing and said fuel tube, said movable joint comprising a tubular seat formed on said housing and defining a longitudinal axis, and a boss formed on said fuel tube so as to be disposed within said tubular seat, said boss including a contact surface that is in sliding engagement with said tubular seat and is rotatable about an axis that is perpendicular to said longitudinal axis.
A fuel nozzle comprising:
- a fuel tube having a first end and a second end, said fuel tube having a bend formed therein so as to define first and second sections on opposite sides of said bend;
- a housing disposed around said fuel tube so as to enclose said fuel tube including said bend;
- a fixed joint between said housing and said first section of said fuel tube;
- and
- a movable joint between said housing and said first section of said fuel tube that permits relative sliding and rotation between said housing and said fuel tube.
A fuel nozzle comprising:
- a fuel tube having a first end and a second end, said fuel tube having a bend formed therein at a location intermediate said first and second ends;
- a housing disposed around said fuel tube so as to enclose said fuel tube including said bend and to define an air gap therebetween;
- a first movable joint between said fuel tube and said housing at said first end of said fuel tube;
- a second movable joint between said second end of said fuel tube and said housing;
- and
- a fixed joint between said fuel tube and said housing located between said bend and said first end of said fuel tube, adjacent to said bend.
