The principle of these loading systems always remains that of compression, and subsequent expansion to suck the ink from the bottle, of a rubber sac; therefore, the general considerations on advantages and disadvantages made in the previous paragraph apply. The substantial difference is in the mechanism with which the compression is carried out, however also in this case it is generally made use of a rigid pressure bar, pressed by the mechanism of the lever, to distribute uniformly the pressure on the sac.
