ABSTRACT:
A valve arrangement from microstructured components worked out of a basic body, for the control of fluids, include an actuation element which is movable relative to a flow path distributor and opens or closes fluid paths depending on its position. A transition from one position into the other is effected by adding an actuating drive connected to an electrical power source. The actuation element is held in its switch position. For a high fluid flow, a large force can be applied to the actuation element. The actuating drive works according to an operating principle aimed at covering the longest distance possible. A holding device is provided, which works according to an operating principle working independent of the first operating principle and provides the generation of the greatest cohesion possible.
