    I came across the term "vented valves" with regard to cornet/trumpet valve sets today. Can anyone explain how this works?

    Cheers

    Thanks - very interesting. I can see how it might be possible to vent an existing valve by drilling a small hole in the appropriate place on a valve body(don't try this at home, kids!), but surely that's not how the valve-set makers would do it? Perhaps by slightly overlapping the ports so that the valve "leaks" in the up position?

    I'm pretty sure Bauerfiend (sp?) make vented valves but for the life of me I can't find a website...
