SYSTEMS AND METHODS FOR CREATING A SEAL ABOUT A LIQUID FUEL INJECTOR IN A GAS TURBINE ENGINE
First Claim
1. A fuel nozzle assembly for a gas turbine engine, comprising:
- a fuel injector comprising an outer jacket having a first end and a second end with a threaded surface disposed therebetween, wherein the first end of the fuel injector comprises a cylindrical sealing surface; and
an annular hub comprising an aperture having a first end and a second end with a threaded surface disposed therebetween, wherein the aperture is configured to at least partially house the fuel injector therein and comprises a conical seat about the first end, wherein the cylindrical sealing surface swages inward along the conical seat to form a seal therebetween as the liquid fuel injector is threaded into the aperture.

Abstract
A fuel nozzle assembly for a gas turbine engine is disclosed herein. The fuel nozzle assembly may include a fuel injector including an outer jacket having a first end and a second end with a threaded surface disposed therebetween. The first end of the fuel injector may include a cylindrical sealing surface. The fuel nozzle assembly also may include an annular hub including an aperture having a first end and a second end with a threaded surface disposed therebetween. The aperture may be configured to at least partially house the fuel injector therein and includes a conical seat about the first end. The cylindrical sealing surface may swage inward along the conical seat to form a seal therebetween as the liquid fuel injector is threaded into the aperture.
