Pressure control solenoid valve
1. Electric Connector - 2. Fuel outlet - 3. Fuel inlet.
Positioned at the inlet of the high pressure pump, enables to
control the quantity of fuel feeding the pump according to
the controls received by the electronic Central Unit. In the
absence of control signal, the valve is normally open, there-
fore the the high pressure pump is in maximum delivery con-
dition.
The Central Unit sends to the controller a PWM control sig-
nal in order to choke in a greater or lesser way the inlet sec-
tion of the fuel to the high pressure pump.
This component cannot be replaced individually and there-
fore must not be disassembled.
Low pressure limiter valve
Assembled in parallel to the pressure control solenoid
valve,has the function to keep inlet pressure constant to the
value of 5 bar, that is a necessary condition for a correct
operation of the control system.
