| 摘要 |
<p>The present invention relates to a valve assembly for dispensing liquid from a container. A manifold (62) includes a first channel extending downwardly from a first inlet (80) to a first side outlet (82). A second channel extends downwardly from a second inlet on the manifold to a second outlet, the first side outlet and the second inlet located on the same horizontal plane in reference to the longitudinal axis of the manifold. An elastic membrane (66) sheathed around the manifold extends over the first side outlet and the second inlet. In a first embodiment external fluid pressure causes the membrane to expand under fluid flow to provide for fluid communication through the manifold. In alternate embodiments fluid pressure flowing through the first and second channels causes the elastic membrane to expand enabling fluid communication between the first side outlet and the second inlet.</p> |
