Abstract
A regulation device and method for regulating an air flow, a gas flow or an equivalent medium flow in which slats can be moved to form an adjustable flow passage in their interior and have lateral edges overlapping each other. The cross-sectional flow area of the flow passage defined by the slats in their interior is adjustable by displacing the slats. A wire is passed around the slats and is displaceable so as to displace the slats and thus regulate the flow passing through the flow passage defined by the slats.
