Abstract
The oxygen breathing controller of the present invention provides a first inlet regulator and a second inlet regulator. The first inlet regulator is provided with a poppet with a diaphragm around its perimeter, and the second inlet regulator is controlled by a servo pilot regulator. The oxygen breathing controller is provided with a low flow control which controls the flow of oxygen below approximately 10 lpm at altitude below 34,000 feet at suction pressure of less than 2.5 inches of water. Above 34,000 feet of altitude or breathing suction pressures of above 2.5 inches of water, the servo pilot regulator controls the second stage valving assembly.
