摘要: A filling system for a fountain pen includes a pump unit, an air channel connected to the pump unit and to a first connection for connecting to the fountain pen, and an ink channel separate from the air channel and having an immersion end for immersing in ink and which is connected to a second connection for connecting to the fountain pen. The pump unit is designed to introduce a specified air volume into the air channel with positive pressure in order to flush ink out of the fountain pen and subsequently apply a negative pressure to the air channel such that a specified ink volume is suctioned out of the ink channel into the fountain pen.

摘要: A fountain pen with a quick-filling coupling includes a nib assembly, a housing with a main tank and a writing tank formed therein, a rotatable finial at an end of the fountain pen opposite from the nib assembly, and a coupling for placing the housing on an ink feed device. A first sealing unit, arranged between the writing tank and the main tank, can be selectively opened and closed for filling the writing tank via the main tank. A second sealing unit, arranged between the writing tank and the nib assembly, can be selectively opened and closed for supplying ink to the nib assembly. A third sealing unit, arranged between the main tank and the coupling, can be opened and closed for filling at least the main tank. The finial is operably coupled to the pen for controlling the opening state of the first and second sealing units.
