Abstract

The air flow through a ventilation duct (1) of rectangular cross-section is controlled by a row of shutters (3) mounted on parallel shafts (2). Each shutter (3) has an end plate (12) with teeth (23) which mesh with the teeth of the end plate of the adjacent shutter so that all the shutters rotate simultaneously. An end seal is formed by a flat ring (14) of soft rubber which is compressed between the end plate (12) and the wall of the duct (1). The shutter edges (7) press against sealing strips attached to adjacent shutters.
