Abstract

PURPOSE:To provide the high efficiency and the miniaturization for the liquid jet device by constructing the whole unit with the piezoelectric element. CONSTITUTION:By etching the piezoelectric ceramic base of PZT series, pressure room 12, flow path 13, nozzle 14 and liquid tank 15 are formed on the base, and the symmetrical another base is united on with some method. Electrodes 21, 22, 23 are set up by metalization etc. When an electric pulse is applied, the liquid is jeted through the nozzle 14 with the sudden reducing the volume of pressure room 12. Therefore, the construction of the whole unit with the piezoelectric element leads the high efficiency, the miniaturization and the simplification due to the unit itself changing the volume of pressure room.
