摘要: A bidirectional valve for medical use or the like provides different threshold opening pressures in different directions using a valve seat and flapper construction providing improved characterization in operation in contrast to cross-slit valves often used for bidirectional operation. A valve disk supported in a central annular region provides movable portions engaging in valve seats at a peripheral region and a central region.
