3232877 - 1060E diesel pressure pump
Pressure pump
It is "radial jet" type with three radial pistons (total capacity 0.657 cc) and is driven by the timing belt without requiring synchronization.Each pumping unit consists of:
- a piston (5) operated by a cam (2) fixed to the pump (6) shaft
- an inlet valve (3)
- a supply ball valve (4).

8, Supply - high pressure (rail)
9, Supply - low pressure (recirculation)
Pressure regulator
It is fitted on the pressure pump and is operated by the injection control unit and regulates the fuel supply pressure to the injectors.The pressure regulator basically consists of:
- a spherical shutter (1)
- a valve (3) control pin (2)
- a pre-loading spring (4)
- a coil (5).
