Abstract: A fluid dispensing apparatus (20; 20') that may be additive manufactured as one unitary piece and may be a fuel injector (20) for a gas turbine engine includes a radial displacement bellows (58; 58') having an outer surface that faces and may be exposed to a surrounding environment and an interior surface that faces and may define at least in-part a flowpath (64) extending along a centerline (52). The radial displacement bellows (58; 58') is constructed and arranged to move between an expanded state (74) when a pressure differential between the environment and the flowpath (64) is low to a restricted state (72) when the pressure differential is high.

Abstract: A tube assembly that may be for a fuel nozzle (20) of a fuel system of a gas turbine engine may have a first tube (56) defining a first flowpath (59) along a centerline (52), a second tube (58) generally spaced radially outward from the first tube (56) with a first void (60) located between and defined by the first and second tubes (56, 58), and a support structure (68) located in the first void (60) and extending between the first and second tubes (56, 58). The support structure (68) is constructed and arranged to minimize or eliminate thermal conduction between the tubes (56, 58). The entire assembly may be additive manufactured as one unitary piece. One example of a method of operation may include designed-for breakage of the structural support (68) due to thermal stresses thereby further minimizing thermal conduction between tubes (56, 58).
