A valve for regulating the flow of fluids (gas or liquid) using two flexible
diaphragms
in which an additional element is added to promote rolling contact between the
diaphragms. The valve operates in a normally open configuration where fluid flows
into the valve, passed through holes or openings in two electrostatically operative
diaphragms and out of the valve. The holes or openings in one diaphragm are offset
from the holes or openings in the other diaphragm, so that upon electro-static
actuation, the diaphragms will seal together, closing the valve.
