ABSTRACT:
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.
