Abstract
The preferred embodiment of the invention is a fluid pressure alleviating pneumatic or hydraulic system component. The invention is comprised of a diaphragm, carrier and a release mechanism. The diaphragm is attached to the carrier. The release mechanism bears against the diaphragm and positions it such that fluid pressure on the surface of the diaphragm produces only or primarily shear force at the connection between the carrier and the diaphragm. The connection and parts have sufficient strength so that the fluid pressure can not shear the diaphragm from the carrier. When the fluid pressure becomes excessive the release mechanism, under force, retreats and allows the pressure of the fluid medium to translate the diaphragm into a position relative to the carrier that will invoke peel force between the carrier and the diaphragm. The characteristic of the joining method is such that it is much weaker in a peel mode than in a shear mode so that the fluid pressure is able to peel the diaphragm from the carrier and allow fluid medium to escape past the diaphragm.
