Claim:
1. A pressure-driven valve, comprising: a housing comprising a fluid inlet and a fluid outlet; a fluid flow channel extending between the fluid inlet and the fluid outlet; and a deflectable portion disposed within the housing, the deflectable portion defining a portion of the fluid flow channel and being configured to deflect to increase and decrease a size of the fluid flow channel to regulate fluid flow from the fluid inlet to the fluid outlet, the deflectable portion comprising a first side subject to fluid flow pressure in the fluid flow channel, and having a second side facing away from the first side, the second side subject to an outlet pressure representative of pressure at the fluid outlet, the deflectable portion being disposed and arranged to deflect as a result of pressure differentials between a reference pressure, the fluid flow channel pressure, and the outlet pressure.
