IIRC, Al, it did not extend to the generation of vacuums. I know of three separate instances where a team used 100% FRC-legal pneumatics to generate a vacuum via mechanical means. (2 in 2004 and 1 in 2007). All three were judged legal. It is possible to argue that this system creates 2 vacuum systems.

You could also make the argument that this effectively creates 2 closed-loop gas shocks, which have a rather off-and-on legality if I remember the past rules correctly. (Of course, then that begs the question of "Why not just do that on one cylinder instead of two?", but that's beside the point.)

And remember, now that we are in a bit of a rules discussion: 2010 rules may forbid pneumatics altogether or otherwise make this design either legal or illegal, so anything said here may or may not apply after 1/9/2010.

Seeing as the rookie teams KOP will come with a Air Compressor I have reason to believe that pneumatics will be legal.

Don't tell them, but that's the ballast next year. The pneumatics come back in 2011.
