Abstract
A fuel conduit for a fuel injector includes a coiled tube with a longitudinal segment arranged along a flow axis and a radial segment. The radial segment extends about the flow axis and is in fluid communication with the longitudinal segment. The wall one or more of the longitudinal and radial segments increases at a thickness transition location offset from a minimum radius of curvature location along the fuel conduit to limit stress within the fuel conduit. Fuel injectors and methods of making fuel injectors are also described.
