The fresh gas reservoir is only active in the semi-open mode.
It is bypassed in the open mode.
The opening at the bottom of the plastic container conveys the fresh gas
out of the unit in the case of damage to the bellows.
Filling and emptying the bellows is controlled by solenoids on the valve
block, depending on the set ventilation parameters.
