The quick exhaust mechanism is inherently a check valve.
Do you think a different part of R77 applies to quick exhaust valves? |
After further review of the rules, I don't believe that a quick exhaust valve is legal this year. It has been ruled illegal in the past in Q&A, and I don't see any explicit allowance for it this year. I was basing my assumption of legality on
your earlier post.
A quick exhaust valve is an assembly of parts, one of which is a check valve, but while it
contains a check valve, it is not a check valve, any more than a pneumatic cylinder is a piston, or a car is a transmission.
