Abstract
A gas turbine fuel injector assembly including one or more dampers for damping vibration of one or more fuel conduits in the assembly. The dampers may at least partially surround the fuel conduits, and each damper has an intermediate portion that is bowed relative to axial end portions to form a pocket, which enables the damper to be free to flex radially for damping vibration experienced by the fuel conduit during operation. The damper may be a wire mesh damper formed with interwoven wires that are configured to move relative to each other in response to vibrational movement of the fuel conduit. The wire mesh damper also may enable fluids, such as gases or fuel, to flow through gaps in the wire mesh. The damper may support and damp individual fuel conduits, thereby enabling the fuel conduits to thermally expand independently of each other in the assembly.
