Abstract: A goose neck style vent has a base that registers with a surface opening of a building, and upstanding walls which form a portion of a curved air flow pathway above the vent opening. A top portion of the vent registers with the base to complete the curved air flow pathway and define an air outlet opening. The top includes a screen that hinges to cover the air outlet opening. A flapper valve is positioned across the curved air flow pathway and is hinged to the base at one end. The opposite free end of the flapper valve is urged to a closed position by gravity and to an open position by air pressure from below. An upstanding air deflecting baffle extends above the free end of the flapper, and limits air gusts passing through the screen and under the free end of the flapper valve.
