David , what a useful drawing to explain the principle of a double beat valve . Could Dave Collidge copy it onto the relevent part of the archive ?

Of course Bob, but I think I can do better, as this is only a cut from a drawing. I have more showing the seats etc in detail. When I get home I'll see what I can do.

thank you very helpful,
