Fuel Manifold Valve - Continental Motors TSI0L-550-C Operation, Maintenance & Installation Manual

Fuel Manifold Valve

The fuel manifold valve distributes fuel to the fuel
injector nozzle in each of the six cylinders
The fuel manifold valve body contains a fuel inlet,
a diaphragm chamber, and outlet ports for fuel
lines to the individual fuel nozzles. The spring
loaded diaphragm carries a plunger in the central
bore of the manifold body. The diaphragm is
enclosed in 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 diaphragm chamber to
its base and to the valve within the plunger. As fuel
flow increases, pressure overcomes the diaphragm
spring tension causing the plunger to move to the
open position and allowing fuel to flow from the
manifold valve outlets through fuel lines to the fuel
nozzles.
