Abstract

The damper blade (10) forms a zigzag-shaped pattern in cross-section, and is terminated by a part (8) inclined in relation to it. Such parts meet in the closed position so that the blade termination are parallel with an intermediate seal (9). The same seals locate against the damper frame.
