Classification: CPC F  B  Y | IPC B  F

Claim 0:
1. An assembly for an engine, comprising:
a liner extending circumferentially about an axis, a combustion chamber formed by and radially within a radial inner liner surface of the liner;
an outer wall extending circumferentially about and spaced radially from the liner;
a fuel line extending circumferentially within the outer wall;
an injector throat fluidly coupled with the fuel line, the injector throat angularly offset from a radial inner wall surface of the outer wall by an acute angle in a radial plane with respect to the axis, the injector throat further angularly offset from the radial inner liner surface by the acute angle in the radial plane, the radial plane parallel with the axis, and the injector throat configured to direct fuel received from the fuel line into the combustion chamber through a throat outlet;
a webbing projecting radially inward from the outer wall towards the liner, the webbing forming the injector throat, and the webbing configured with a triangular cross-sectional geometry in the radial plane;
a compressor rotor comprising a plurality of compressor blades, the compressor rotor rotatable about the axis; and
a turbine rotor comprising a plurality of turbine blades, the turbine rotor rotatable about the axis and disposed axially between the compressor rotor and the injector throat along the axis;
wherein the triangular cross-sectional geometry has a first side, a second side and a third side;
the first side is at the outer wall and extends along the axis;
the second side is adjacent and extends parallel to the injector throat;
the third side forms a distal side of the webbing exposed to a plenum radially between the outer wall and the liner; and
the throat outlet is located on the third side and faces an opening in the liner, and the throat outlet is configured to inject the fuel into the plenum.
