Abstract (en)

[origin: DE19631693A1] The valve arrangement comprises two silicon wafers placed on top of each other. The downstream wafer contains a majority of etched through openings (6). The upstream wafer (3) is equipped with a majority a swing valves (7). The latter are modelled by etching the silicon and are located in through frame openings (8). They are connected to the wafer (3) by membrane-type webs (9) enabling elastic opening and closing movements. The individual swing valves (7) contain differing amounts and differing sizes of through openings (6), thereby enabling a widely adjustable range of dynamic pressure and flow control through selective actuation of the valves. The swing valves (7) are actuated by electrical means, resulting in capacitive forces of repulsion and attraction.
