TDR masses:
I am working on a small presentation for the last project of my college career on spring-centered and detented directional control valves. Several hours of internet search has left me with nothing of use except the names of every hydraulic and valve manufacturer known to the web.
What I am looking for would be an explanation of the aforementioned valves, and thier differences, schematics would be a wonderful thing.
Any links you might be able to provide would be worth thier weight in gold, otherwise it's off to the library. :{ TIA.

Guess I should say I already checked howstuffworks and tried several different search variations on the valve parts.
