Translations:Bulb filler/4/en

This allows you to repeat the pressure on the pump several times, to perform different filling actions and progressively fill the pen. In the absence of the breather tube in fact, with the compression of the pump, the ink present in the barrel would escape, since there is no vent for the air contained in the same, thus obtaining a very limited capacity; the breather tube instead provides a way out to the air present in the tank that is compressed by the pump, and a way in for the ink that is sucked in by the depression. In this way it is possible to repeat the compression of the pump and continue to load ink until the latter does not exceed the level of the breather tube, completely filling the pen.
