Patent ID: 8870020

Claim:
A closure device for use in providing an emergency degassing function, a pressure equalization function, and a condensate removal function for a housing sealed off from an environment, the housing being adapted to hold a technical component, the closure device comprising: a frame fastenable to an opening of the housing, the frame having a frame opening; a closure element operatively configured to close the housing opening, wherein the closure element is at least one of configured and arranged relative to the frame such that: in a first closure position, at least one path is formed in or through the closure element via gravitational force acting on the closure element, the at least one path allowing for an exchange of air and a discharge of condensation water between an interior of the housing and the environment; in a second closure position produced by water impinging on the closure element from the environment, the at least one path is closed in a sealing manner; and upon exceeding a specified overpressure of the interior of the housing relative to the environment, the closure element being detachable from the frame opening, wherein the closure element is pivotably fastened to the frame at a first side edge in the first and the second closure positions, the closure element being fastened in a form or force-fitting manner to the frame at another side edge, and wherein the form or force-fitting connection is disconnectable when the specified overpressure is exceeded to allow for a pivoting movement from the first or the second closure position into a detached open position.
