Title: Perforated Fluid Balancing
Authors: Dilan Fernando, Sean Fitzsimons, David Price
Disclosed is a device to prevent a fluid filled bag from trapping the fluids inside. pressure is applied to a fluid bag create fluid pockets, thus trapping pinched, thus trapping fluid user having to intervene. Even fluid trapped in pockets formed away from the nozzle area need to be funneled to the nozzle.
Another issue with fluids such as inks are particulate dropouts or other contaminants bags getting to sensitive areas of the machine. In the case of printers, the affected areas maybe printheads and intermediate ink reservoirs
The disclosed invention is a rigid perforated tube running the length of the (Figure 1). This perforated tube proposed design, there are many perforations to allow for ample fluid flow with a heavy-duty filter (Figure 2).
An alternative such as a flexible spring of design has limitation, where the spring not be as efficient as the rigid one. important that the tube be somewhat flat, in order to minimize fluid wastage, when the bag/cartridge is completely flatten
