ABSTRACT:
A manifold valve assembly for selectively interconnecting a row of ports to control the flow of fluid in a group of lines coupled thereto. The assembly includes a valve block having a like row of cylinders formed therein which communicate at their lower ends with the row of ports. The upper ends of the cylinders are interconnected, whereby fluid admitted into any one cylinder flows into the other cylinders in the row. Supported coaxially within the cylinders is a corresponding row of expandable tubular nipples, the ends of the nipples in their unexpanded state reaching a first point. Projecting into the nipples are a group of push-button actuated rods. Each rod, when pushed in by its associated button causes the nipple to expand to reach a second point in the cylinder. A valve seat in each cylinder cooperates with the end of the nipple therein to cut off fluid flow in the cylinder when the nipple end reaches one of the points to engage the seat, flow being resumed when the nipple end is shifted toward the other point.
