Abstract

Vorrichtung zur Gasmengenregulierung in von Gas durchströmten Rohren (6), insbesondere in von Luft durchströmten Rohren (6) einer Lüftungsanlage, mit einer Vielzahl von in Strömungsrichtung (7, 8) des Gases ausgebildeten Parallelkanälen (2) und einer Einrichtung (10) zum zumindest teilweisen Verschließen der Parallelkanäle (2), wobei die Parallelkanäle (2) jeweils einen solchen Durchmesser aufweisen, daß die Reynolds-Zahl der die Parallelkanäle (2) am Austrittsende verlassenden Gasströme kleiner 2.000, vorzugsweise kleiner 1.800, noch mehr bevorzugt kleiner 1.500 ist.
