The one in the middle of the picture with the green mark on it. I've looked at the parts diagram and can't figure out what it does.
That is an factory adjusted pressure valve. There is a spring that maintains pressure on a small ball bearing that controls fluid pressure. It is held in place by the stud and fixed with the nut. Rotating the stud clockwise or counter-clockwise changes the seat pressure of the ball. Forget you ever saw this unless of course you did see it and played with it then we would need to expand the conversation.
