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;
- a conduit extending between 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 the conduit define between one another a flow area that is smaller in the plunger second position than in the plunger first position, and wherein the plunger has a blunt segment, a tapered segment, and a constant diameter segment coupling the blunt segment to the tapered segment, wherein the tapered segment is tapered from a wider end to a narrower end in a direction away from the blunt segment.
