    摘要: A microvalve in multi-layer structure is proposed, where an inlet connector, a return connector and an outlet connector are produced by planar structuring of material layers. The microvalve has a first and a second stage, which is disposed behind the first stage in respect to the flow direction of the fluid. In the first stage the flow direction of the fluid is directed into a cavity formed by two chambers by means of a flexible tongue, which in the position of rest is oriented parallel to the flow direction of the fluid. At least one outlet connector is disposed in the second stage.

    摘要: A microvalve composed of multiple layers bonded together is distinguished by the fact that all layers are structured only from one side. Prior to bonding of a new layer to the preceding layer, the new layer is homogeneous or unstructured. Only after bonding of the new layer to the preceding layers or wafers is the newly-applied layer provided with a structure, by etching or other profiling method. This simplifies construction, and reduces manufacturing cost, of the microvalve. The valve can be used for either liquid or gaseous media. It is adapted for use, inter alia, as a fuel injection valve or as a pilot control stage of servo-valves used in anti-lock braking systems (ABS). A method of producing a sealed cavity with a residual gas pressure therein, which may have applications other than valve manufacture, is also disclosed.
