The big chrome thing that you can spin is an IC valve. Zodiac innovation. It allows you to fill two chambers from one point. You can spin to select A, B, A+B, or none.
To deflate, you unscrew the cap and you unscrew the insert.
The inserts and caps are made of either delrin or nickel-plates brass.
If properly adjusted and lubricated, the IC valve will act as an over pressure valve. Pull outward on the chromed flywheel and you'll see what I mean.
