[Craig Close adds:]

I figured someone like Ed K could give a dissertation on valve gear.
Thanks for the reasoning, Ed.  There is a set of DOS (Gasp!) programs
which produce graphical diagrams of many types of running valve gear
designs.  These programs can be found at:

They are pretty clunky, but that may be just what the Doctor would order
when we non-engineering types ask about valve gears.
