They seemed to have had a mechanism which while the main chamber was deflated to push air to the wearer of the mask – via the breathing hose, the smaller front bellows inflated ready to push air out to the wearer of the mask at the action of re-inflating the main chamber. This would allow the wearer of the helmet to have a constant air supply on the up-stroke and down-stroke.
