Abstract
940,749. Respiratory apparatus. BRITISH OXYGEN CO. Ltd. Aug. 29, 1962 [July 5, 1961], No. 24386/61. Heading A5T. [Also in Division F4] A liquid oxygen breathing apparatus for use in aircraft comprises first and second liquid oxygen supply lines 16, 17 extending from a liquid oxygen converter 10 to crew and passengers respectively, the outlet 14 to the second supply line being at a higher level than the outlet 13 to the first supply line, a build-up circuit 18, 22, 23 being connectable with either supply line through a multiport changeover valve A which is biased towards a first position, in which it isolates the second supply line and connects the build-up circuit with the first supply line, and which is normally held by a catch (not shown) in a second position in which it connects the second supply line with the build-up circuit, the catch being releasable in response to reduction in pressure below a predetermined value so that the valve is moved to its first position and the changeover valve being manually returnable to its second position. The fall in pressure which releases the catch occurs when the liquid oxygen in the converter has fallen below the level of the passenger supply outlet 14 and causes the valve to cut off oxygen from the passengers, supply to the crew continuing. Non-return valves 20, 21 and vaporizing coils (not shown) are disposed in each supply line. The changeover valve A includes a rotatable body arranged in a housing having a port 25 connected with the build-up circuit which includes a combined, build-up filler and vent valve 18 and a pressure closing valve 24, ports 27, 28 connected in the second supply line and a port 29 connected to the first supply line. Normally excess pressure developed in the converter is released to atmosphere through a relief valve (not shown) but in a modification such pressure is released through a pressure opening valve (Fig. 2, not shown) into the first supply line.
