Abstract
A pressure relief valve for structure. A valve with a spoiler around its edge sits in a valve seat around a structure valve aperture, and is spring-loaded into a closed position. Storm wind entering the structure through a breached window, door, or other structure opening escapes through the valve, which opens when exposed to a pressure differential of approximately 1.5 psi. Lift created by storm wind impinging on the spoiler tends to urge the upwind side of the valve closed. The valve may incorporate a skylight. In the preferred embodiment, the shape of the valve was a spherical or spheroid section, and the spring-loading was provided by a plurality of spring assemblies disposed around the edge(s) of the valve.
