Abstract
A manifold valve assembly for selectively interconnecting a row of ports to control the flow of fluid in the lines coupled thereto. The assembly includes a valve block in whose upper face is formed a shallow well. Extending from the well to a plane parallel to the lower face of the block is a row of cylinders whose lower ends define valve seats that communicate with ports projecting from the lower face. A channel indented in the well serves to laterally interconnect the mouths of the cylinders with each other. Seated in the well and sealing the mouths of the cylinders is a pad of elastomeric material from which is projected a row of hollow, axially-expandable nipples that extend into and are coaxially disposed within the cylinders, the nipples all having a normal length that falls short of the valve seats. Mounted above the valve block is an actuator block having a row of tubes therein in axial alignment with the cylinders. Supported in each tube is the retractable push rod of a spring-biased click mechanism. The lower end of each rod protrudes into a respective nipple, the upper end thereof being coupled to a normally-raised push-button. The arrangement is such that when a given b…
