Ah, now I get it.  The rotor in the brochure is not a Judson.

Judson probably used the tangental orientation in an attempt to reduce vane
wear.  Being an automotive application the Judson probably runs hotter than
the compressor in the brochure.  Just my guess.

BTW, I sold my Judsons several years ago.  Tripled my investment and used the
money to buy an Ultralight.  :-)

http://vwjudsonregister.tripod.com/torlon-vane-material.htm has vanes that
radiate outward from the axis of rotation. Dean's rotor has vanes that are
parallel to the axis of rotation - I think I'm saying that correctly.
