Publication number: 20240066866Abstract: According to an embodiment, a liquid dispensing head includes a nozzle plate with a plurality of nozzles and a plurality of pressure chambers respectively communicating with the nozzles. A vibration plate is on a side of the pressure chambers opposite the nozzle plate. A supply-side flow path for liquid to be dispensed from the nozzle is on an inlet side of the plurality of pressure chambers. A discharge-side flow path for the liquid is on an outlet side of the pressure chambers. Piezoelectric elements are positioned to vibrate the vibration plate to change a volume of the pressure chambers for ejecting (dispensing) the liquid from the plurality of nozzles. The supply-side flow path is set to have a flow path resistance that is the same as a flow path resistance of the discharge-side flow-path.Type: ApplicationFiled: June 9, 2023Publication date: February 29, 2024Inventors: Taiki GOTO, Masashi SHIMOSATO, Noboru NITTA
