Dunno how old it is. Seems to work well except for an annoying
problem described on the web page above. [3rd stage over-pressure valve
pops repeatedly]


I would guess non-compressibles in the high pressure section are
being vented off...

Duh. Makes perfect sense. The right amount of oil or oil/water
emulsion would do it, wouldn't it? It's an old beast, probably
heavily used for many years. And oil mist does blow out when the valve
pops.

But it never occurred to me that the amount of oil reaching that stage
could make that difference.

--definately beats the alternative.

Yeah. Oh, yeah.

Thanks,
