ABSTRACT:
A vent assembly for attachment to a fluid discharge conduit of the type connected to a clothes dryer, room exhaust fan, or the like is adapted to reduce or prevent the trapping of dirt or lint as well as flapping or vibration of the door in windy conditions. A mount having an opening is received on the conduit and a door is pivotally received by the mount. The door is operable for displacement with respect to the opening between an open position and a closed position when engaged by a fluid, such as air from a clothes dryer, flowing through the discharge conduit. A hood is pivotally mounted over the door and mount opening, and is operable for displacement with respect to the mount when engaged by the door and/or by fluid flowing through the discharge conduit.
