Abstract
A closure device provides an emergency degassing function, pressure equalization and condensate removal for a housing sealed off from the environment. The closure device has a frame, fastenable to a housing opening and having a frame opening, as well as a closure element, for closing the housing opening. The closure element is configured or arranged relative to the frame such that a path is formed in or through the closure element in a first closure position by the gravitational force acting on the closure element. The path enables an exchange of air between the housing interior and the environment as well as a discharge of condensation water. A second closure position, in which the path is sealed closed is producable by water impinging on the closure element from the environment. If a specified overpressure is exceeded, the closure element is detachable from the frame opening.
