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