Abstract
A valve assembly is provided with concentric fluid paths and may be used on a hydrogen generator to transport liquid reactant to the hydrogen generator and hydrogen gas. The valve assembly includes a housing defining first and second fluid paths, a first valve member disposed in the first fluid path, and a second valve member disposed in the second fluid path. The assembly includes a connector including a first elongated member configured to engage the first valve member to open the first valve member to allow a first fluid to flow through the first fluid path, and a second fluid port including a second elongated member configured to allow fluid to flow through the second fluid path. The valve assembly is concentric in that the second fluid path surrounds at least a portion of the first fluid path.
