Abstract:
A liquid circulation apparatus includes a main tank that stores a liquid, an upstream tank connectable to an upstream side of an inkjet head, a downstream tank connectable to a downstream side of the inkjet head, a pump configured to supply the liquid from the main tank at an amount larger than a sum of an amount of liquid passing through the inkjet head and an amount of liquid ejected from the inkjet head. The upstream tank includes a first upstream liquid chamber configured to be at a hydrostatic position higher than a nozzle of the inkjet head and connected to the pump, a second upstream liquid chamber configured to be connected to the inkjet head, and a third upstream liquid chamber connected to the main tank. The downstream tank includes a first downstream liquid chamber configured to be at a hydrostatic position lower than the nozzle.

Claim (Index 1):
A liquid circulation apparatus, comprising:\n a main tank that stores a liquid; an upstream tank connectable to an upstream side of an inkjet head; a downstream tank connectable to a downstream side of the inkjet head; and a pump configured to supply the liquid from the main tank in an amount larger than a sum of an amount of liquid passing through the inkjet head and an amount of liquid ejected from the inkjet head, wherein the upstream tank includes:\n first, second, and third upstream liquid chambers, which are connected to an upstream air chamber, the first upstream liquid chamber configured to be at a hydrostatic position higher than a nozzle of the inkjet head, the second upstream liquid chamber being adjacent to the first upstream liquid chamber, and the third upstream liquid chamber being adjacent to the second upstream liquid chamber; \n an upstream supply port on the first upstream liquid chamber and connected to the pump, the upstream supply port being below an uppermost portion of the first upstream liquid chamber; \n an upstream delivery port on the second upstream liquid chamber and configured to be connected to the inkjet head; and \n an upstream drain port on the third upstream liquid chamber and connected to the main tank, and \n the downstream tank includes a first downstream liquid chamber configured to be at a hydrostatic position lower than the nozzle and connectable to the inkjet head.
