Translations:Vacumatic filler/2/en

Among the various filling systems based on the use of a breather tube, the Vacumatic is certainly one of the most complex, but in reality it is only a reworking of the mechanism of the previous bulb filler in which instead of using a pump the compression of the air in the body of the pen is done through the movement of a rubber membrane, the diaphragm precisely. In this case the movement is made by pressing a spring button on the bottom of the pen, which acts on the mechanism that moves the membrane. Repeating the pressure several times results in the same pumping result as a normal rubber pump.
