If the solenoid valve (9) is energised by the
electronic unit, the back plate (8) with the valve
(6) will be attracted by the electromagnet due to
the influence of the magnetic field.
The valve (6) closes the connection between the
space above the pump plunger (13) and the
supply ducts (2), causing pressure to build up in
the space above the plunger (13).
This causes the injection.
The fuel will now flow via the fuel supply ducts (2)
to the space above the pump plunger (13).
The valve (6) is not re-opened against the force
of the magnet by the high-pressure in the high-
pressure area, as the forces in the valve (6) slot
are balanced.
In other words, the left and right surfaces in the
valve (6) slot are equal.
The time at which the valve (6) shuts depends on
the injection timing calculated by the electronic
unit.
The time that the valve (6) remains closed, and
therefore the quantity of fuel injected, is also
calculated by the electronic unit.
