Difficult to regulate though - as the same pump affects both. When the high
pressure one is full & low pressure one needs pumping, it'll keep adding
pressure to both (one outside, one inside). You'd have to have some kind of
pressure release valve in both lines.
Unless you use 2 pumps, of course. But then you need 2 "diodes", and 2 feedback
loops, too.

Now as I understand it, the air tank is meant to store (...) (23 years ago, 18-Dec-01, to lugnet.robotics, lugnet.technic, lugnet.build)
