FLUID CONTROL VALVE ARRANGEMENT

摘要

A fluid control valve arrangement includes a plurality of clusters or pairs of holes extending from one face to the other of a central block. The valves comprise a plurality of deformable blisters formed in a resilient membrane, the blisters positioned so as to coincide with the hole clusters or pairs when the membrane is pressed against a face of the block. The values are closed when the blisters are deformed to an essentially flat shape, advantageously by introducing a high pressure fluid into a cavity above the blisters. The valves are linked together in a desired configuration by grooves formed in the other face of the block.
