Re: Quick Question
Jason, I believe you've just described the process behind a double-expansion steam engine. There are triple and quadruple steam engines still in existance today. Each cylinder in sequence is larger, being driven by lower pressure, so that the steam from the boiler is used 2 or 3 or 4 times, making the engine more efficient.
Just a sidebar, nothing to do with the original pneumatic question.
