Abstract:
An inkjet head that is able to circulate ink. The inkjet head includes a diaphragm plate, a first restrictor plate, one or more chamber plates, a second restrictor plate, and an orifice plate. The orifice plate forms a plurality of nozzles. The chamber plates form a plurality of chambers corresponding with the nozzles, and also form a return manifold for receiving ink from the chambers when circulating the ink through the inkjet head. The diaphragm plate forms a diaphragm that seals the chambers. The first restrictor plate controls a flow of ink between the chambers and the return manifold to circulate the ink through the inkjet head. The second restrictor plate controls the flow of ink between a supply manifold and the chambers.
