ABSTRACT:
A bidirectional valve comprising a flexible member with an aperture formed therein. The flexible member reacts to differential pressure thereacross by deforming, thereby causing the inside surfaces of the aperture to separate and create a vent path. The bidirectional valve can be tuned to open the aperture in reaction to varied differential pressures thereacross, thereby allowing a fluid to pass through the aperture.
