Abstract
A purge air and fuel flow divider module () independently directs fuel flow to a plurality of manifolds (and) and independently purges fuel from these manifolds with air when they are not flowing fuel. A secondary manifold () is filled with fuel before flowing metered burn flow to it and fuel flow is apportioned between a primary manifold () and the secondary manifold () during secondary manifold metered burn flow. Three manifolds are disclosed, a primary manifold (), a secondary manifold () and a start or pilot manifold (), each containing fuel nozzles (). A manifold main housing () contains a purge valve () and two three-way solenoids () controlling respectively a secondary transfer valve () and a pilot nozzle transfer valve (). Depending on the requirements, the solenoids position the valves to either provide manifold fill fuel, burn flow fuel or purge air to their respective manifolds. When fuel is shut off to the manifold, the purge valve () is remotely commanded to purge the primary manifold () with air.
