Fuel distribution valve for a combustion chamber

摘要

A fuel distribution valve 16 for a gas turbine engine is disclosed. Various construction details are developed which improve the ability of the combustion chamber 12 to avoid blowouts of the combustion chamber. In one particular embodiment, the fuel distribution valve has ports 38 for controlling the fuel flow to fuel nozzles 14 in the combustion chamber. The ports provide equal flow area at high engine power, high aircraft Mach number (greater than 0.8M) operation while providing unequal flow areas at certain preselected low power operative conditions of the engine which follow the high power operative condition.
