interconnected flap shafts are closed by means of vacuum by the intake manifold switchover diaphragm unit.
When the variable intake manifold switchover valve is open, the vacuum is supplied from a vacuum reservoir
with check valve in the intake manifold. The reservoir volume is designed for about 5 operations without
renewed evacuation.
The variable flaps open by means of spring force.
