Patent ID: 8464740

Claim:
A flow divider assembly, comprising: a dividing valve comprising: a dividing cavity configured to receive a flow of fuel, the dividing cavity including a first dividing valve port and a second dividing valve port, and a piston device arranged within the dividing cavity and selectively positioned to divide the flow of fuel in the dividing cavity such that a first portion of the flow is directed into the first dividing valve port and a second portion of the flow is directed into the second dividing valve port; and a balancing valve fluidly coupled to the dividing valve and configured to receive the first portion of the flow at a first pressure and the second portion of the flow at a second pressure, the balancing valve comprising: a balancing cavity including a first balancing cavity port and a second balancing cavity port, 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, wherein the piston device comprises a rod and a first piston and a second piston arranged in fixed positions on the rod, and wherein the first piston, second piston, and rod are configured to translate with one another within the dividing cavity such that the first piston selectively blocks the first dividing cavity port and the second piston selectively blocks the second dividing cavity port, wherein the dividing cavity further comprises a third dividing cavity port and a fourth dividing cavity port, and wherein the dividing cavity is fluidly coupled to the second balancing valve port to receive the second portion of flow and is further configured to divide the second portion of flow such that a third portion of flow is directed into the third dividing cavity port and a fourth portion of flow is directed into the fourth dividing cavity port.
