I think that it does not cycle under normal operation, but I haven't 
ever thought much about it. My guess is that if it really cycled 
much, then the brass bellows would fatigue rather quickly and fail 
much sooner than we normally observe.

OTOH, I'm guessing that the "step function" can't really be all than 
sharp, so there's room for the system to be open different amounts 
for different conditions.

Good food for thought.
