Ok, I get it... sorta.
Can someone then enlighten me: what purpose does this flapper mechanism serve? If it's normally in the closed position (I.e., when the engine is cold), to me that would appear to block exhaust expulsion on one side of the engine. That can't be a good thing, can it??
Also, I conducted an experiment to see what happens when heat is applied to the coiled spring element. It CONTRACTED when heated, but the hook RECEDED AWAY from the mechanism that is supposed to force the flap open. So I'm confused... even though it sounds like I won't need it in my application. I'd still like to understand it, though. 😁
