Abstract

PURPOSE:To form a valvular part capable of improved sealing property and responsive velocity by providing a valvular means of a nozzle consisting of a laminated piezoelectric ceramics which blocks nozzle holes when one fixed end of the valvular means expands, and a sealing member which is installed at the free end of said means and hermetically seals the nozzle holes. CONSTITUTION:A valvular means 10 has a constantly set application voltage and expands to an arrow direction prior to the operation to set a pump ON and a valve OFF. Then one end of the valvular means 10 expands to a nozzle direction because one end of the valvular means 10 is fixed to a keep plate 20, and the nozzle holes 51 are set to a closed state by means of a sealing member at the free end. At that time, a laminated piozoelectric ceramics can obtain a significant displacement at a small application voltage. Next, the valvular means 10 contracts to a vertical direction by setting the pump ON and the valve OFF, and further overlapping pulse voltage to the constant application voltage. Subsequently, the free end at the tip of the valvular means separates from the nozzle holes, and ink is sent flying from the nozzle holes 51 in the form of ink droplets under the ink pressure of an ink liquid chamber 70, for recording on paper.
