Service manual

The delivery valve, through which a shot of fuel is
forced out into the injection pipe by each upward
motion
of the plunger, is essentially a check valve
having a special function
of qUickly reducing the
line pressure the moment the plunger begins to
descend. This quick relief
of line pressure is
necessary to prevent the injection nozzle from
dribbling at the end
of each injection. How this is
accomplished will become clear.
