If the air consumption is less than the maximum air output, air receiver pressure increases and the regulating valve
supplies control air to throttle valve (TV) to reduce the air output and holds air receiver pressure between the normal
working pressure and the corresponding unloading pressure. Unloading pressure = normal working pr 1 bar
(14.504 psi).
When the air consumption is resumed, the blow off valve (BOV) closes and the throttle valve (TV) gradually opens
the air intake and the electronic speed regulator increases the engine speed.
The construction of the regulating valve (RV) is such that any increase (decrease) of the air receiver pressure above
the pre-set valve opening pressure results in a proportional increase (decrease) of the control pressure to the throttle
valve and the electronic speed regulator.
Part of the control air is vented to atmosphere, and any condensate discharged, through the vent holes (VH).
