Very interesting. Thanks.

Actually the problem goes away if you consider the whole ship as an
engine with different pressure levels. One just uses seals as for
instance the rings in a piston which keeps the explosive pressure
levels in the firing cylinders out of the oilways.

Then there are the various oil seals that keep the oil out of places it
isn't needed and stop it from splattering everywhere when it gets to
where it is.

Have you posted it to the various military groups?

Oooh, I spent hours and hours in there a couple of years ago. Splendid
stuff. And most of it largely comprehensible - unlike many modern
systems.

IIRC you'd struggle to find even a diode.
