ABSTRACT:
Method of regulating ink flow in automatic drafting pens of the type supporting a plurality of stylographic pens in parallel, including pumping ink from a reservoir into the writing pen capillary tubes, gauging the level of ink intermediate the reservoir and the capillary tubes and modifying said pumping as the gauged, actual level of ink flow may deviate from a desired level of ink flow. The method includes buffering of ink flow into the capillary tubes, so as to overcome the effects of inertia (when the pen is not writing), as well as the surge of ink flow under pumping pressure.
