Abstract

A device that equalizes an aircraft pressure difference has a separating wall, fixable to the aircraft, and a decompression valve. The wall is for fluidically separating first and second spaces, and has a flow opening that fluidically connects the spaces. The valve closes the flow opening. A securing element on the valve or wall enables a release of the valve when a pressure gradient between the spaces is exceeded, such that there is a fluidic connection between the spaces. The receiving element on the wall or valve is connected to the receiving element. The securing element has a rotary element and fixing elements. The rotary element is rotatably mounted about a rotational shaft. The rotary element is receivable in the receiving element. The fixing elements non-rotatably fix the rotary element beneath the predetermined pressure gradient. At least one of the fixing elements is a spring.
