I now think the mechanism is simpler than before.
To the right is the outlet to the print head. In the middle is the filling tube. To the left is the breather tube and breathable film.
The bottles have some kind of seal to prevent ink release until they are pushed onto the filling tube. When pushed on the bottle to tube interface is air tight.
When pushed on ink flows from the bottle into the tank until enough vacuum is pulled in the bottle above the ink. After that air from the tank needs to bubble up the filling tube to displace more ink flowing into the tank. You hear the 'glugging' noise while that happens.
When the tank ink level reaches the bottom of the filling tube it blocks air bubble formation and flow stops.
When the bottle is removed the ink in the filling tube flows into the tank.
So even when the tank ink level is above the end of the filling tube inserting the bottle will cause enough to pull the vacuum and a filling tube full of ink to flow into the tank.
If you insert the bottle repeatedly the tank will be over filled and if ink reaches the breathable film will be ruined requiring the tank to be replaced.
