I've been told that many pneumatic cylinders have thin
walls that would be able to handle some of the depths we go to, if there is
not enough pressure inside them. So in that mode they would be acting like a
vacuum tank, like are subs hulls are on 1 ATM boats. So having the heavy duty SS
ones like Vance mentioned would be a good plan. I'd be interested in what models
of Bimba cylinders will fit are needs.

that I did up those sketches. Brent, thanks for digging those out.
You can purchase the Bimba actuating cylinders in stainless steel with an option
for spring loaded so that the valve will fail in the closed position (i.e. loss
of control air pressure). R/Jay Resepectfully, Jay K.

Yes that is the one I was thinking of. Very simple. I might try and use
it. Thanks Hugh |
