Description of working principles
Fuel is sucked from the fuel tank by the priming pump. This
last one is placed on the engine basement and is driven by
the camshaft.
Throughout the filter, the fuel is piped to the union fitting
vacuum chamber of the transfer pump. (For applications to
be equipped in cold climate areas, the fuel filter is provided
with heater).
Transfer pump is placed inside the feed pump, and is bladed
type; its duty is to increase fuel pressure in correspondence
with the increase of the number of revolutions.
The fuel arrives therefore to the valve gauging the pressure
inside feed pump.
The distribution plunger further increases this pressure and
delivers fuel throughout the delivery pipe fitting
to the
injectors.
The fuel drawing from the injectors is recovered and delivered
to the tank again.
