Abstract
An ink delivery regulation apparatus includes a support configured to be positioned within an ink chamber and a resilient deflection member coupled to the support. The resilient deflection member is configured to resiliently deflect from a generally concave shape to a generally convex shape in response to a change in said negative pressure.
Claims43
An ink delivery regulation apparatus, comprising:
- an ink chamber configured to contain a quantity of ink;
- a support configured to be coupled to said ink chamber;
- and
- a resilient deflection member coupled to said support, said resilient deflection member extending into said ink chamber and occupying a volume thereof, said resilient deflection member being configured to resiliently deflect between a generally concave shape and a generally convex shape in response to a change in a negative pressure in said ink exterior to said resilient deflection member, said resilient deflection member comprising a plurality of pressure tuned panels disposed at angles with respect to each other.
