CENTRIFUGAL PUMP FUEL SYSTEM AND METHOD FOR GAS TURBINE ENGINE |
摘要 |
A fuel system for a gas turbine engine that utilizes a centrifugal pump. The system includes a fuel metering valve that is adapted to set a metered flow of fuel, and a throttle valve that is adapted to accurately control pressure drop across the fuel metering valve. The throttle valve has at least two variable orifices and a compensation chamber between the variable orifices. The throttle valve includes a differential valve piston slidable in a valve body. The differential valve piston comprises working surfaces of at least two different diameters such that changes in chamber pressures effect different axial forces upon the piston.
