STIMULATOR/FILTER DEVICE THAT SPANS PRINTHEAD LIQUID CHAMBER

摘要

A jetting module includes a nozzle plate, a thermal stimulation membrane, and an enclosure. Portions of the nozzle plate define a nozzle. The thermal stimulation membrane includes a plurality of pores. The enclosure extends from the nozzle towards the thermal stimulation membrane to define a liquid chamber positioned between the nozzle and the thermal stimulation membrane. The liquid chamber is in fluid communication with each of the nozzle and the plurality of pores. The liquid chamber is spanned by a portion of the thermal stimulation membrane. A source provides a liquid under pressure through the thermal stimulation member with the pressure being sufficient to jet a stream of the liquid through the nozzle after the liquid flows through the thermal stimulation membrane.
