Fuel shut-off valve

The fuel shut-off valve is installed on the upper
side of the distributor-type injection pump in the
vicinity of the fuel injection lines. This solenoid
valve interrupts the fuel supply when the engine
is shut down.
Functional description
The valve is open when no power is applied. In
this way, it keeps the inlet hole to the high
pressure chamber open. When power is applied
to the solenoid, the valve closes the inlet hole.
The fuel supply is shut off so that the high
pressure piston can no longer deliver fuel.
Substitute function
None
Effect
The engine is shut down by the metering adjuster.
