Air distribution chamber shutter - has hinge axis inside line joining outlet edges

摘要

The shutter for an air-distribution chamber has the hinge axis (D) situated inside the line (K-M) joining the opposite edges of the outlet. The actuating arm (E) can be shorter than the distance between the edges, and the shutter itself (G) can hinge on the arm, on which lugs (F) can be formed, to give a guiding action and also a locking one. The shutter can have a self-cleaninq action.
