1. A passive dual modulating regulator with relative differential venting (“regulator”) comprising:
a housing defining a first hydrogen chamber, a second hydrogen chamber, a third hydrogen chamber opposite a first oxygen chamber, a second oxygen chamber, and third oxygen chamber;
a first valve assembly comprising a first piston slidably engaged with, and extending between, the first hydrogen chamber and the first oxygen chamber, wherein a pressure differential between the first hydrogen chamber and the first oxygen chamber causes the first piston to move towards a chamber of lesser pressure, such that the first piston restricts and then seals a hydrogen outlet port or an oxygen outlet port to equalize pressure between the first hydrogen chamber and the first oxygen chamber;
a second valve assembly comprising a second piston slidably engaged with, and extending between, the second hydrogen chamber and the second oxygen chamber, wherein a threshold pressure differential between the second hydrogen chamber and the second oxygen chamber due to excess pressure in the second oxygen chamber causes the second piston to overcome a first biasing element and release oxygen through an oxygen vent port; and
a third valve assembly comprising a third piston slidably engaged with, and extending between, the third hydrogen chamber and the third oxygen chamber, wherein a threshold pressure differential between the third hydrogen chamber and the third oxygen chamber causes the third piston to overcome a second biasing element and move toward a region of lesser pressure in the third oxygen chamber and release hydrogen through a hydrogen vent port.
