Abstract
A fuel divider system includes a housing assembly and a flow passage network having an inlet, a primary outlet, and a secondary outlet. A fuel divider piston is slidably disposed within the housing assembly and movable between a flow biasing position and a flow equalizing position. A control chamber is fluidly coupled to the flow passage network and fluidly communicates with the piston. An inlet chamber, at least partially defined by the piston and the housing assembly, is fluidly coupled to the inlet. At least one channel is provided through the piston and configured to cooperate with the flow passage network to port the FD control chamber to: (i) the fuel pressure at the secondary outlet when the FD piston is in the flow biasing position, and (ii) the fuel pressure within the inlet chamber when the FD piston is in the flow equalizing position.
