Abstract
The smoke disperser unit has a double-walled liner (2) for the discharge duct. This liner has inner (6) and outer (7) sub-frames, inside an external main frame (8). An insulated layer (10) is provided around the opening and a seal (11) is fitted. Between (7) the inner and outer sub-frame is mounted an electromagnetic solenoid valve (15) for releasing the drop flap. The solenoid is protected from the effects of the fire and operates a catch (14, 14'). The drop flap (3) is mounted on hinges (4) and has an inflatable seal (16) onto the liner and is fitted with two similar shock absorbers (12), one on either side.
