Radial piston pump - High pressure pump (2)
Fuel reaches the piston intakes of the high pressure section via the opened solenoid valve .
The cam ring, du to its elevations, presses the piston radially toward the centre of the pump . It
compresses the fuel by every lift for the injection into the respective cylinder.
Text-module
High pressure solenoid valve (4)
Controlled by the pump control module( A020 ), regulates the fuel supply for the high pressure radial
piston pump.
The High pressure solenoid valve defines the injection volume and the injection rationg (Injection
volume per degree of cam setting) for every individual injection.
The high pressure solenoid is monitored by the pump control module !
Text-module
Distribution shaft with distribution body (3)
The shaft distributes fuel in such a manner that every cylinder will be supplied once via the injection line
fiting for each pump rotation.

return flow valve (integrated in the injector line fitting) (5)
damps the shockvawes wich occr by the shutting of the injectors.
