Abstract
A fuel injector for a gas turbine engine includes a feed arm defining a conduit extending between an inlet end and an outlet end and a plunger. The plunger is disposed within the conduit and is movable between a plunger first position and a plunger second position. A flow area defined between the plunger and the feed arm is smaller in the plunger first position than in the plunger second position to bias fuel flow through the fuel injector. Fuel systems, gas turbine engines, and methods of controlling fuel flow in gas turbine engine fuel systems are also described.

A fuel injector for a gas turbine engine, comprising:
- a feed arm defining a conduit extending an inlet end and an outlet end;
- and
- a plunger disposed within the conduit and movable between a plunger first position and a plunger second position,
- wherein the plunger and conduit define between one another a flow area that is smaller in the plunger second position than in the plunger first position.
A method of controlling fuel flow in gas turbine engine fuel system, comprising:
- flowing fuel in a feed arm having an inlet end and an outlet end through a conduit extending between the inlet end and the outlet end of the feed arm, and
- moving a plunger disposed within the conduit between first and second positions within the conduit, wherein movement between the first and second position reduces fuel flow through the fuel injector by reducing a flow area defined between the plunger and the feed arm.
