This pressure can be higher or lower than the one of the air in the environment, but (...) (23 years ago, 18-Dec-01, to lugnet.robotics)

Also, the external pressure is usually fairly fixed (atmospheric pressure) and there's a lower limit to the internal pressure (absolute vacuum), but no intrinsic upper limit (though it is limited by the strength of the tank). Therefore a (...) (23 years ago, 18-Dec-01, to lugnet.robotics, lugnet.technic)

Also, it's real hard to make vacuum, in the real world. I once built a (...) (23 years ago, 18-Dec-01, to lugnet.robotics)
