<p>PRESSURE RESPONSIVE VALVE STRUCTURE A novel pressure responsive valve structure is provided, which includes a housing having at least one aperture for enabling communication between the interior and exterior of the housing. A first duct, for carrying fluid to the valve, terminates within the housing, and a second duct, for carrying fluid from the valve, also terminates within the housing. A diaphragm is affixed in the interior of the housing between the aperture and the duct terminations. The diaphragm is moveable to cover the terminations when the pressure at the aperture exceeds the pressure in the ducts, and is moveable from off the terminations when the pressure in the ducts exceeds the pressure at the aperture.</p> |
