ABSTRACT:
A flexible one-way valve is produced by cutting two flexible members having identical peripheral configurations and a maximum width intermediate opposite ends and the peripheral edges are secured to each other to produce valve portion having an inlet opening along the point of maximum width, an outlet opening at one end. The remainder of the peripheral edges are left unattached so that the unattached portions define a support which can extend perpendicular to the axis of the valve. The valve portion preferably has a reduced area opening or throat between the inlet opening and the outlet opening.
