ABSTRACT:
A diaphragm assembly for movement in response to a pressure increase exerted thereon comprised of a resilient flexible diaphragm having a first surface with a predetermined profile when said diaphragm is in a neutral, unflexed condition, the diaphragm having an opening formed therethrough.
A rigid pressure plate is adapted to be positioned against the diaphragm. The plate has a contoured surface for mating engagement with the first surface of the diaphragm. The contoured surface has a recessed sealing surface dimensioned to form an open space between the plate and the diaphragm when the diaphragm is in the neutral, unflexed condition, and to enable the diaphragm to flex into sealing engagement therewith when sufficient pressure is exerted on said diaphragm. A first vent passage communicates the opening in diaphragm with the open space, and a second vent passage communicates the open space with the edge of the pressure plate.
