If the air consumption is equal to or exceeds the maximum air output, the engine speed is held at
maximum load speed and the throttle valve (TV) is fully open.
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.
