A method for manufacturing a stem for a fuel injector of gas turbine engine includes forging a material into a unitary workpiece, which includes forging a top disk having a cylindrical shape, forging a body extending from a base of the top disk, and forging a lower disk connected to the body, distal to the top disk, the lower disk having a cylindrical shape oriented transverse to the top disk. The method further including machining the lower disk to form a gas gallery having a ring shape, and to define a gallery opening through the gas gallery, and machining a first fluid passage through the top disk, the body, and a portion of the gas gallery to the gallery opening, wherein the first fluid passage is in fluid communication with the gallery opening.

Forged fuel injector stem

A swirler inlet valve plate for a fuel injector of a gas turbine engine includes a blocker ring and a pivot sleeve mechanically connected to the blocker ring. The blocker ring is formed from at least a portion of a toroid shape. The blocker ring includes a blocking surface perpendicular to an axis of the blocker ring formed from at least a portion of an annulus. The blocker ring also includes a flow surface, an inner circumferential surface of the toroidal shape. The pivot sleeve includes a sleeve portion extending adjacent the blocker ring. The sleeve portion includes a rotation transmission mechanism.

Pivoting swirler inlet valve plate

A gas turbine engine fuel injector stem includes a single piece of material with a flange, a center body, a gas gallery, and a fluid passage. The flange includes a cylindrical shape, a plurality of mounting holes and a handle hole. The center body extends from a flange cap in the flange axial direction. The gas gallery is adjacent the center body and distal to the flange. The gas gallery includes a ring shape oriented transverse to the flange and includes a gallery opening. The fluid passage extends through the flange, center body, and gas gallery and is in flow communication with the gallery opening.

An exhaust treatment system is provided. The system may include a particulate trap configured to remove one or more types of particulate matter from an exhaust flow, the exhaust flow including at least a portion of a totality of exhaust gases produced by an engine. The system may further include a burner assembly configured to increase a temperature of gases in the exhaust flow at a location upstream from the particulate trap. The burner assembly may include an exhaust inlet oriented in a direction along a first axis and configured to direct the exhaust flow into the burner assembly and an exhaust outlet oriented in a direction along a second axis at an angle relative to the first axis, the exhaust outlet being configured to direct the exhaust flow out of the burner assembly toward the particulate trap.
