Combustor fuel control systems with flow divider assemblies

摘要

A flow divider assembly includes a dividing valve and a balancing valve. The dividing valve includes a dividing cavity configured to receive a flow of fuel and a piston device arranged within the dividing cavity and selectively positioned to divide the flow of fuel in the dividing cavity into the first dividing valve port and the second dividing valve port. The balancing valve is fluidly coupled to the dividing valve and configured to receive the first portion and the second portion of the flow. The balancing valve includes a balancing cavity and a balancing device arranged within the balancing cavity and selectively positioned to direct the first portion of the flow into the first balancing cavity port at a third pressure and the second portion of the flow into the second balancing cavity port at a fourth pressure such that the first pressure is approximately equal to the second pressure.
