Abstract
A check valve for placement in a fluid conduit, includes a separator element with at least one opening; the opening allows fluid flow through the separator element. A pliant sealing member is attached to a downstream side of the separator element, covering the opening. During forward flow, this pliant sealing member deforms, allowing fluid to pass around it. However, during reverse fluid flow, this pliant sealing member flattens and covers the opening, preventing reverse fluid flow through the opening.
