FIGURE 13-2. GENERAL FUEL MANIFOLD VALVE DESCRIPTION
Fuel manifold Valve (See Figure 13-2)
The fuel manifold valve body contains a fuel inlet, diaphragm chamber and outlet ports for
fuel lines to the individual nozzles. The diaphragm is enclosed by a vented cover which
retains the diaphragm loading spring. When the plunger is down in the body bore, fuel
passages to the nozzles are closed off. The plunger is drilled for passage of fuel from the
fuel inlet chamber to its base. As fuel flow increases, pressure overcomes diaphragm
spring tension causing the plunger to move to the open position and fuel flows from
manifold valve outlets through fuel lines to the fuel lines to the fuel nozzles assemblies.
