A vent assembly for rapidly depressurizing a compartment in an aircraft upon accidental depressurization of another compartment, including an apertured grille through which a circulation of return air normally passes, but which is mounted to swing into a hollow wall of the aircraft to pass a greatly increased flow of depressurizing air into the wall when desired. Two actuator plates are hinged together for differential pressure induced relative pivotal movement, and act upon such movement to swing the grille to its open or venting position. The hinged plates form a wall of a plenum chamber behind the grille, and the normal circulation of return air is so directed as to flow first through the grille, then through the plenum chamber, and then into the interior of the hollow wall beyond the plenum chamber to thereby assure positive and direct exposure of the plates to a change in compartment pressure.
