<p>A self sealing valve includes a diaphragm (602) positioned within a valve housing (606) by a movable hanger arm (610) which suspends the diaphragm from a mounting point (612) in the center of an air inlet (614). The hanger arm (610) is a rotating diaphragm hanger that has one end secured adjacent to an inner wall (618) of the air inlet (614) by a pair of pins (634). There is a contoured section (648) between the hinge pins (634) of the inner wall which interfaces with a contoured end (650) to provide for at least four distinct interaction possibilities. A first retains the hanger arm (610) in a valve closed position. A second causes the valve to exhibit a biased closed condition. A third locks the valve open and a fourth facilitates assembly.</p> |
