A pressure relief device extends between the double side walls of a passenger compartment of an airplane to communicate with an adjacent cargo compartment. A duct is formed between a perforated section of an inside wall and a panel extending from the inside to the outside wall. A spring closing, pivotally mounted valve extends across to close off the duct and has perforations to permit air flow through the closed valve at low pressure differential between the compartments, but the valve will open at sudden high differential pressures.

A pressure relief device in an airplane to provide decompression relief between a passenger compartment having a double side wall and a cargo compartment, the device comprising: a grill to replace a section of an inside wall; ductwork to extend from an upper edge of the grill to an outer wall to form a channel for movement of air between the two compartments; and a pivotally mounted valve to extend across to block the channel, said valve having resilient means sized for holding the valve closed under normal operating conditions and having perforations sized to allow pressure equalization across the closed valve in response to a low pressure differential and to require the valve to open in response to a high pressure differential.
