<p>A rapid response self-closing pressure equalization vent 10 employs a frame 12 supported in a compartment divider and a movable vent portion 16 having a periphery sealingly engaging the frame 12 in a closed position. Multiple resilient extension elements 30 are attached to the frame 12 and engage the movable vent portion 16 for even displacement around a periphery of the movable vent portion 16 relative to the frame 12 to an open position responsive to a pressure differential on the movable vent portion. The resilient extension elements 30 retract upon equalization of the pressure differential to reseat the movable vent portion 16 in the frame 12.</p> |
