8.2.4 Main clamping action
The oil flow coming from the pump is completely directed into the main pressure
chamber via VD2.
The voltage coming from the control module via the amplifier card of VW1 will be
transformed into a power signal and reflects the pressure in the main chamber which
is proportional to the set value in the touch screen.
