Abstract
A mesovalve having a diaphragm situated between a first chamber and a second chamber. There may be an inlet and an outlet in the first chamber. The diaphragm may provide an orifice between the first and second chambers. There may be a first electrode on the diaphragm and a second electrode on an inside surface of the second chamber. The diaphragm may have first and second positions, or numerous variable positions. Applying a voltage across the electrodes may electrostatically move the diaphragm to the second position during which the outlet is at least partially opened for fluid communication with the inlet, the orifice is closed and the diaphragm is stopped in the second position by a cushioning fluid pressure in the second cavity to prevent pull-in. Removing the voltage from the electrodes may let the diaphragm return to the first position, open the orifice and close the outlet.
