Abstract

The invention relates to a barrier for preventing rats or other vermin from entering a sewage pipe system. The barrier has a shutter (1, 30, 31) pivotally suspended in the barrier about an axis and having a centre of gravity lying under the axis. The shutter (1, 30, 31) is pivotal between a first angular position (v) in which the at least one shutter is forming a first relatively larger angle with the direction of flow and at least substantially barring the aperture of the barrier, and a second angular position (w) in which the at least one shutter is forming a second relatively smaller angle with the direction of flow keeping the aperture of the barrier at least partly open. Preferably, a second shutter is placed upstream of a first shutter and is pivotally suspended about a second axis and having a centre of gravity located under the second axis.
