ABSTRACT:
A combination pressurizing valve (27) and fuel flow divider for a gas turbine is operable in three different fuel distribution modes utilizing three windows which are successively opened to control the flow distribution to the engine atomizing or start-up nozzles (23) and engine air blast or running nozzles (25) respectively by way of two fixed orifices (51, 55) in a way that satisfies the start-up flow distribution favoring the atomizing nozzles (23) as well as the need for balanced flow distribution between the different types of engine nozzles after a successful start. The first window position corresponds to an engine ignition mode and includes a range of intermediate valve spool (33, 133) positions where one outlet port (57) is open and the other outlet port (67) receives a restricted flow of fuel. The second window position includes a range of valve spool (33, 133) positions where the one outlet port (57) is open and the other outlet port (67) is open to receive a flow of fuel greater than the restricted flow. The third window position corresponds to a full power engine condition and includes a range of valve spool (33, 133) positions including the another extreme position where the one outlet port (57) is open and the other outlet port (67) is open to receive a still further increased flow of fuel.
