Oxygen breathing controller having a G-sensor

摘要

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.
