Abstract:
A device for controlling the flow of a liquid or gaseous medium, has at least one flow opening for the medium, and a movable valve element for controlling the flow opening. At least one damping body, which is preferably viscoelastic and acts on the valve element, is provided for obtaining a large dynamic range of the device in order to control flow in a fine, precise, and oscillation-free manner across a broad range of flow volume.
