Title: Improvements in or relating to breathing apparatus
Inventor: FITT PETER WILLIAM
IPC: A62B9/02
Filed: 1956-06-16
Abstract: 830,341. Breathing apparatus. NORMALAIR Ltd. May 24, 1957 [June 16, 1956], No. 18711/56. Class 81 (2). A demand regulator for breathable gas comprises a respiratory responsive member controlling a demand valve, the responsive member having one surface subjected to breathing pressure and the other surface alternatively to ambient pressure or to pressure greater than ambient pressure, and means for varying the pressure on the side of the responsive member remote from the breathing pressure. In the demand regulator shown in Fig. 1, oxygen passes from an inlet 6 to an outlet 7 in communication with a breathing chamber 8 under the control of a demand valve 3 operated by a diaphragm 2; on the opposite side of diaphragm 2 from the breathing chamber is a closed chamber 10 containing a spring 11 which provides a light loading on the diaphragm 2 to maintain the pressure in chamber 8 slightly higher than that in chamber 10. Associated with the regulator is a valve body comprising two spring-loaded valves 13, 14 attached to a common spindle and provided with an adjusting screw 18. A duct with a reduced orifice 20 connects breathing chamber 8 to the valve 13 and a further duct connects chamber 10 to a chamber 22 between valves 13 and 14. In operation at low altitudes control knob 18 is adjusted so that valve 13 is closed and valve 14 open putting chamber 10 in communication with chamber 23 which is exposed to ambient pressure. When greater pressures are required control knob 18 may be adjusted to close valve 14 and open valve 13. Chambers 8 and 10 then communicate with each other and oxygen flows from chamber 8 to chamber 10 tending to equalize the pressures in the two chambers; thus diaphragm 2 is subjected to an increased surface pressure and the regulator operates as though ambient pressure were increased accordingly, until excess pressure in chamber 10 is released by the opening of valve 14 against its spring, the opening pressure being determined by the spring loading imposed.
