Abstract
Abstract A one-way fluid valve formed of a parallel plurality of one-way valve cells, each cell comprising three flexible leaflets each bonded to 1/3 of the edge of a hexagonal opening in a frame, their free center edges joining to close upon pressure from one side and separating to open the valve upon pressure from the opposite side of the frame.
