Turbine shaft fuel pump
This patent describes a turbine engine having a support housing, a shaft rotatably mounted in the support housing, an annular combustion chamber coaxial with the shaft and the support housing, the shaft having an axial passageway, injector nozzles aligned for discharging fuel into the combustion chamber, and means for pumping and metering a supply of fuel to the injector nozzles, the pumping and metering means. It comprises a flow passageway extending from a first end of the shaft axial passageway and to the injector nozzles the flow passageway comprising an annular chamber formed between two axially spaced and radially inwardly extending walls in the shaft, the annular chamber is open to the axial passageway while a periphery of the annular chamber is open to the injector nozzles, and pumping vanes disposed in the annular chamber, the vanes being secured to the shaft so that, upon rotation of the shaft, the vanes provided pressurized fuel from the passageway to the injectors.
