Abstract
A fluid control valve includes a cover portion and a body portion. Inner surfaces of the cover and the body portion define a chamber that includes an inlet and an outlet in communication with the chamber. The cover portion includes a central section and an inversion inhibitor circumscribing the central section. The inversion inhibitor projects into the chamber toward a central axis of the chamber. The fluid control valve also includes a diaphragm disposed between the cover portion and the body portion. The diaphragm has a flexible member that is disposed within the chamber for controlling communication between the inlet and the outlet. The inversion inhibitor prevents the flexible member from reaching its natural-inverted position and creates a force within the flexible member that urges the flexible member to a seated position. In the partially inverted position, the upper surface of the flexible member conforms to at least a portion of the inner surface of the cover portion to define a passageway that permits communication between the inlet and the outlet.
