Abstract (en)

[origin: EP0919778A2] A vent comprises a duct (16) defining a vent passageway having a vent passageway exit and a vent cover (24) movable between a first aperture position and a second aperture position in which the vent passageway exit is fully covered and is not fully covered, respectively. There is an aperture (140) in a duct side wall which is closed when the vent covers (24) is in the first operative position and open to allow air to pass to or from the vent passageway through the aperture when the vent cover (24) is in a third operative position in which the vent passageway exit is also fully covered. The vent cover (24) may be a second vent cover, which are interlinked so as to be constrained to move together, either towards each other to cover the vent passageway exit or away from each other to uncover the vent passageway exit. In this latter embodiment the operative is optional. <IMAGE>
