Claim 15:
16. A fuel injector comprising:
a manifold that defines a fuel gallery that is annular around an injector axis, wherein the manifold comprises an outer wall, and an inner arm that is annular around the injector axis and positioned within the fuel gallery, wherein the inner arm includes a first axial portion, and a first curved portion that curves radially inward, relative to the first axial portion, to define a first space, between the first axial portion and a radially inner surface of the fuel gallery, with a sealed aft end;
an outer arm that is annular around the injector axis and positioned within the fuel gallery, wherein the outer arm includes a second axial portion, and a second curved portion that curves radially outward, relative to the second axial portion, to define a second space, between the second axial portion and a radially outer surface of the fuel gallery, with a sealed aft end; and
a distributor plate that is annular around the injector axis and positioned between the first axial portion and the second axial portion to divide the fuel gallery into a forward region and an aft region, wherein a radially inner edge of the distributor plate is bonded to the first axial portion, wherein a radially outer edge of the distributor plate is bonded to the second axial portion, wherein the distributor plate comprises a plurality of apertures extending from a forward side of the distributor plate to an aft side of the distributor plate, and wherein each of the plurality of apertures is configured to allow fuel to flow from the forward region to the aft region of the fuel gallery.
