Abstract (en)
[origin: WO0231362A2] A method for filling a printing ink reservoir with a housing (1) is disclosed, the interior of which is divided into two chambers (3, 4), by means of a metallic bellows (2), serving as a medium separator. The first chamber (3) is filled with a gas and the second chamber (4) is filed with a fluid. A bottom valve (6) is provided n a hydraulic connection (5), the closing body (7) of which may be operated by the medium separator (2), permitting a filling of the second chamber (4) with fluid and preventing a complete emptying of the second chamber (4). According to the invention, a reliable filling of the said chambers (3, 4) with the corresponding medium may be achieved without damaging the bellows (2), by means of a combination of the following method steps: a) evacuation of the second chamber, b) filling the second chamber with printing ink and c) filling the first chamber with the gas.
