The most important component of the fuel-delivery regulator is a linear solenoid whose armature acts directly on the control rod thus determining the injection volume by means of the control position.
When no current is supplied, the control rod is held in the stop position by means of a spring. The pilot feed / start of delivery regulator also contains a linear solenoid, whose armature, by means of an adjusting lever, causes the control-slider adjusting shaft to rotate. When no current is supplied, the adjust- ing shaft is also held in position by a spring, so that the control-slider is in its uppermost position, in the “late” start of delivery position. The regulator also has a control rod position sensor and an oil pump (viscous pump). PIN: 2 3 4 7 8 5 6 1 RWG R RWG Y RWG M MES 0 MES 1 MVS 0 MVS 1 Designation:
