Abstract

A fire damper in a ventilation duct comprises a flap 12 which is pivotably mounted in the duct 2 for movement from an open position, allowing air flow along the duct, to a closed position to inhibit air flow or the passage of flame along the duct. The flap 12 is pivotally mounted on a round cross section axle 14 which extends through the duct wall and a motor unit 32 is mounted on the end 14b of the axle for rotating of the flap 14, the motor having a polygonal socket 26 for receiving the shaft end 14. A protuberance formed by a pin 40, 46extending through the shaft 14 is provided on the shaft surface for engagement with the socket wall to cause the axle to rotate with the socket 26. <IMAGE>
