Abstract
A fuel nozzle valve includes a fuel nozzle valve liner having a channel with an opening for allowing fuel to flow therethrough and a seat. A plunger has a stud and a base substantially perpendicular to the stud, the plunger being configured to move relative to the fuel nozzle valve liner to seal or to open the opening of the fuel nozzle valve. The fuel nozzle valve further includes a metal resilient member configured to contact the base of the plunger and the seat of the fuel nozzle valve liner to seal the opening of the fuel nozzle valve when the plunger is moved to seal the fuel nozzle valve.

A fuel nozzle valve comprising:
- a fuel nozzle valve liner having a channel with an opening for allowing fuel to flow therethrough, and a seat;
- a plunger having a stud and a base substantially perpendicular to the stud, the plunger being configured to move relative to the fuel nozzle valve liner to seal or to open the opening of the fuel nozzle valve;
- and
- a metal resilient member configured to contact the base of the plunger to seal the opening of the fuel nozzle valve when the plunger is moved to seal the fuel nozzle valve,
- wherein the metal resilient member is attached to a wall of the fuel nozzle valve liner and the metal resilient member remains attached to the wall of the fuel nozzle valve liner when the plunger is moved to open or to close the fuel nozzle valve.
A turbine engine comprising:
- a fuel nozzle valve comprising:
- (a) a fuel nozzle valve liner having a channel with an opening for allowing fuel to flow therethrough, and a seat;
- (b) a plunger having a stud and a base substantially perpendicular to the stud, the plunger being configured to move relative to the fuel nozzle valve liner to seal or to open the opening of the fuel nozzle valve;
- and
- (c) a metal resilient member configured to contact the base of the plunger and the seat of the fuel nozzle valve to seal the opening of the fuel nozzle valve when the plunger is moved to seal the fuel nozzle valve,
- wherein the metal resilient member is attached to a wall of the fuel nozzle valve liner and the metal resilient member remains attached to the wall of the fuel nozzle valve liner when the plunger is moved to open the fuel nozzle valve.
