Tractrix valve seats... Any info?
Tractrix valve seats... Any info?
(OP)
I have been delving into the issue of valve seat wear as it relates to tractrix geometry. I came across a paper several years ago and only recently started studying this.

Does anyone have a links to a production example of use of tractrix geometry for valve seats? All I can find is examples of the Wordin stopcock valve. I'm fairly sure it has been used in globe valve before.

I could be the world's greatest underachiever, if I could just learn to apply myself.

a worn but functional engine valve's seating surface bears a superficial resemblance.
