ABSTRACT:
A multi-channel, laminar-flow fluid valve has a base portion, a top portion, and an intermediate gasket portion held together by a centrally-located pivot pin. The top portion is rotatable with respect to the gasket and base portions, and has a circular depression or trough concentric with the pivot pin and adjacent to the intermediate gasket. A series of openings are provided through the top portion, equidistant from each other along the trough. A series of ports, aligned with the series of openings, extend from the outside of the top portion for connection to distribution tubes. Inner and outer ridges, concentric with the pivot pin, project from the gasket portion toward the top portion to fit within the inner and outer edges of the trough, respectively. Smaller circular ridges, fitting between the inner and outer ridges, are positioned to align with the series of openings through the top portion. A hole through one of these small circular ridges and the gasket aligns with another port extending from the other side of the intermediate gasket, and projects through a hole in the base portion for connection to a tube. As the top is rotated, each of the distribution tubes is coupled, in turn, through the hole in the gasket to the bottom tube. The other distribution tubes are sealed off.
