a Recirculated air flap closed
The supercharger is permanently driven over a poly-V belt by the crankshaft.
The charge pressure is controlled by the recirculated air flap actuator which is located at the intake/recirculated air opening of the supercharger.
If the air recirculation flap is closed, the engine will have the full boost pressure made available to it.
The recirculated air flap is always closed at full load.

M16/7 Air recirculation flap actuator
b Recirculated air flap open
If the recirculated air flap is open, the boost pressure air is guided back via the recirculated air line to the supercharger.
The air recirculation flap can be adjusted continuously from 0 to 90° and can regulate the boost pressure over the recirculated air line.
