Awhile ago, I was trying to figure out exactly how an air regulator worked.
Well, I did.  But now that brings me to a question.

I have a "mini" regulator on my compressor to control the air pressure.
The air flow through a system will be dependant on the size of the various
orifaces, ie air hose.  But what about the regulator?  The mini regulators
have pretty small holes - I didn't measure it, but I'd say no more than 
1/8" in dia. for the air to got through the regulator.

Do the larger regulators have larger holes in them?  It would seem that
using the "mimi" regulators or a regulator restrict the flow of air to
a tool.  Consiquently, if the compressor were capable of flowing 9cfg at
90psi how can you be sure the regulator will pass 9 cfm?
