ABSTRACT:
A fast acting mechanical valve (2) affords macroeffects with high speed, low mass, micromovement. A first microporous planar sheet-like electrically conductive film (4) has an electrically insulative face surface (6), and an array of microapertures (7-11) through the film and face surface. A second microporous planar sheet-like electrically conductive film (12) abuts the insulative face surface and has an array of microapertures (13-16) therethrough nonaligned with the first array. An electric circuit (26, 28 and 30) supplies electric current flow through the parallel films to effect relative transverse movement therebetween due to interacting electromagnetic fields, for actuating the valve between closed and open positions.
