Help: Carabiner Auto-Lock Mechanism

I have a couple questions about the auto-locking carabiners. What does the spring mechanism look like inside? The concept of the auto-lock biner I understand. But how do all the parts fit together inside the gate?

Could anyone share a diagram or drawing of what's inside? Maybe someone has taken one apart to see what's going on inside. Pictures would be great.

Here are a couple examples of the type of auto-lock gate I'm referring to:

I can't find pictures, but i'm sure it's very simple. Something like, the sleeve that locks the gate has a spring wound underneath it. The spring is attached to both the gate and the sleeve such that the spring has tension both for rotating and sliding actions. The slot you can see on the outside of the sleeve holds the end of the spring.

All the ones in your photos.... are AUTO-UNLOCKS.

Just let the rope run the wrong way across any of those... your unclipped!!!!

beware

Thank you for your replies!

Not that I don't believe this is possible, but it seems like a highly unlikely set of events would have to come together in the correct sequence to unlock that biner automatically. A much more difficult set of events than a regular biner.

Those diagrams explain a lot...

All these years I thought there were unicorns inside doing all the fancy locky worky stuff.

ha!

Carabiners like the BD RockLock Twistlock only require one to twist the sleeve and push. If the locker is not free to move, a rope running on the sleve may unclip itself, more or less like one can unclip a rope from a non-locking biner with a flip of the wrist. That is, the rope pushes the gate inward.

Lockers whose sleeve must be pushed up, twisted, and then pushed in are much safer, but it's not clear to me that those shown in the opening post are of that type. I see nothing that would obviously prevent the rotation of the sleeve directly from its position at rest. (I'm not saying that there is nothing; rather that I see nothing.)
