Good idea to start this thread TC. Here's a stat stripped down for anyone who hasn't seen one to ponder on. This one was 11 years old, had done 300k miles and was still operating well, opening at 88C.
You can see that the main valve spring pushes against the bracket when the valve opens, and the smaller spring will allow the smaller valve to seat against the seat as it closes, taking up any overtravel. The 2 valve discs move together until the smaller valve closes completely.
I stripped it to heat the spring up and then re-assemble and test to see if an overheated spring, as mentioned in a previous thread, will make any difference to its opening temperature. Not that I think it will mind.
Will report the results when completed.

Edit: As spotted by blacknwhite the bracket is shown here the opposite way round to how it sits in the thermostat.
