Abstract
A sealing arrangement is provided with overpressure relief. In the preferred embodiment, the sealing arrangement includes a sealing member that is positioned between two housing portions or the like and that is acted upon by the pressure within the housing. A force-responsive retaining arrangement maintains the sealing member in a predetermined location. Upon the occurrence of overpressures exceeding a predetermined value, the sealing member exerts sufficient force on the force-responsive retaining arrangement so as to cause appropriate displacement of the sealing member to permit the venting of the housing.
