Liquid Oxygen

The LOX Converter consists of the major parts:

Container (A)
Combined Filler and Vent Valve with Fill
Port (B)
Pressure Relief Valve (C)
Vaporiser (D)
Outlet Port (E)

All components are mounted on a common mounting plate that is designed for simple replacement at ON Aircraft Level.

The LOX container is consists of two welded shells. Inside the concentric outer shell the spherical inner shell is positioned onto spacers. The space between both shells is highly evacuated so the LOX container is a thermally isolated tank. The container has got pressure connections for the vaporiser and the combined filler and vent valve. A LOX probe is positioned vertically inside the container and measures the LOX content of the container by the capacitive method. The probe consists of two concentric tubes representing the plates of a capacitor connected with a measurement amplifier to stabilise, rectify and amplify the signal, which appears on a moving-coil instrument, the indicator, to show the LOX content of the container to the aircrew.
