The oxygen breathing controller (10) of the present invention provides a two-stage inlet regulator. In addition, the oxygen breathing controller is provided with an aneroid sensor (100) and a G-sensor (80). The G-sensor has at least two diaphragms (92,93) with G-pressure applied to one of them. Pressure control then depends on a ratio between the effective areas of the diaphragms.

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.

Oxygen breathing controller

The oxygen breathing control of the present invention for supplying oxygen to a user employs a first stage regulation module, a valving module which couples with the first stage regulation module, a servo regulator module and an aneroid module. The servo regulator module with oxygen conservation function during exhalation controls oxygen flow between zero to approximately 34,000 feet, and the aneroid module takes over the control of breathing pressure schedule between 34,000 to 45,000 feet. A flow restrictor screw module is employed in the passage between a control chamber and an inlet chamber of the valving module for regulating the flow between the two chambers.
