New Valve Design
 

Check out this valve design:
CSRV System - Coates International Ltd.

Nice.............!

Very Interesting

I've seen these for decades now, no one has been able to make one actually seal and last. Most of the prototypes I've seen were on motorcycle or single cylinder engines.

Very interesting. Why can't they get them to "Seal and Last"?

The gen-sets they run have valve trains that last till the engine overhaul. This is phenomenal. I am going to track down where these are actually in service and chat with them. The company I work for would love this durability
