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.
Claims18
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 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,
- wherein the metal resilient member has a cone shape and is configured to be compressed between the base of the plunger and an edge of the seat of the fuel nozzle valve liner, and a contact surface of the metal resilient member with the edge of the seat is located between an inner edge of the metal resilient member and an outer edge of the metal resilient member.
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 has a cone shape and is configured to be compressed between the base of the plunger and an edge of the seat of the fuel nozzle valve liner, and a contact surface of the metal resilient member with the edge of the seat is located between an inner edge of the metal resilient member and an outer edge of the metal resilient member.
