(5) Operation
(5.1) Injection not taking place
•
With the magnet not energized, the ar-
mature plate is pushed up by the valve
spring such that the ball seat is closed.
•
The high-pressure fuel acts upon the
control chamber via orifice Z. The
same pressure acts upon the nozzle
needle.
•
The fuel pressure acting on the nozzle
needle cannot overcome the valve pis-
ton and nozzle spring, so the nozzle
needle stays in its downward-pushed
position and injection does not take
place.
(5.2) Start of injection
•
When the magnet is energized, the re-
sulting electromagnetic force draws
the armature plate upward, causing
the ball seat to open.
•
Fuel in the control chamber passes
through the ball seat and orifice A and
flows to the fuel tank.
•
With the pressure in the control cham-
ber reduced, the fuel acting on the
nozzle needle overcomes the valve
piston and nozzle spring, pushing up
the nozzle needle such that injection
starts.
•
If the magnet remains energized, the
injection rate reaches its maximum
level.
