PROBLEM TO BE SOLVED: To provide a fuel nozzle (100) corresponding to axial thermal growth, having an ultra-low leakage speed, being robust in vibration environment and having further improved durability. SOLUTION: The fuel nozzle (100) can include: a plurality of concentric tubular bodies (110); and one or more of lip seals (170) positioned between a pair of the plurality of concentric tubular bodies. A fuel nozzle assembly can include a fuel nozzle end cap assembly and the plurality of concentric tubular bodies mounted to the fuel nozzle end cap assembly. The one or more of seal lips can be positioned between the fuel nozzle end cap assembly and the concentric tubular bodies. COPYRIGHT: (C)2011,JPO&INPIT
