A LOX converter consists of a
steel inner and outer shell. If
a leak should develop in the
inner shell an explosion could
occur. Which of the following
components prevents an explosion
from occurring?
1.
Pressure relief valve
2.
Blowout disc
3.
Pressure regulator
4.
Each of the above
6-40.
When servicing an aircraft LOX
system, what prevents liquid from
flowing into the oxygen system
supply port?
1.
One-way check valve
2.
Isolation valve
3.
Filler valve
4.
Two-way check valve
6-41.
During servicing of an aircraft
LOX system, a means for venting
is needed. What valve in the
oxygen system provides this
venting?
1.
Spring-loaded check valve
2.
Pressure relief valve
3.
Vent valve
4.
Filler valve
6-42.
If for some reason the spring
fails to tightly hold the poppet
in the filler port on its seat
after the LOX cart has been
disconnected from the aircraft,
oxygen from an aircraft’s
converter will not escape into
the atmosphere because of what
valve or poppet?
1.
Check valve in the filler
port
2.
Check valve in the converter
supply line
3.
Finer valve supply poppet
4.

What is the purpose of the heat
exchanger in a LOX system?
1. To cool the LOX leaving the
servicing cart to prevent
damage to the aircraft’s LOX
converter
2. To increase the temperature
of the LOX leaving the
aircraft’s converter
3. To prevent damage to the
lungs of the crew member
breathing the oxygen
4. To convert the LOX to gaseous
oxygen
