Abstract
Abstract An X-coordinate manifold, having a plurality of parallel channels extending in the X direction, is mated with a Ycoordinate manifold, having a plurality of parallel channels extending in the Y direction, to form a XY plane manifold. A preselected arrangement of ports, communicating with certain channels, is provided in each manifold, to thereby provide, when the manifolds are so mated, a matrix of paired, aligned ports which are located at the crossing points of certain channels in the X and Y coordinate manifolds. Also, a vertical or Z-channel is made available at the crossing points of certain channels in the X and Y coordinate manifolds. Two or more XY plane manifolds are stacked on top of one another to form a three-coordinate manifold. Gaskets used between the mated coordinate manifolds, and also between the stacked plane manifolds, act as programming devices and also serve as ball retainers for shuttle balls functioning as check valves.
