Abstract
The fountain-pen comprises a large capacity reserve reservoir (3) for the ink, with a piston type valve (14) that can be operated to fill the pen by suction, and a smaller supply reservoir (10) which is adjacent to the nib (5) and supplies ink to it; the piston type valve (14) is provided in order to hermetically close and open the passage between said reserve reservoir (3) and the supply reservoir (10) so as to transfer ink from said reserve reservoir (3) to said supply reservoir (10) and shut off said supply reservoir (10) from the reserve reservoir (3).
