One chamber is the compacting chamber and is sealable from ambient cabin pressure and the other chamber is always open to cabin pressure. The bottom of the compacting chamber is provided with an upper drain and a lower drain. The modified bilge valve provides a fluid path to the atmosphere outside the aircraft.
