Filed: 1987-04-10
Abstract: PURPOSE:To obtain an ink jet head which is characteristic of high air bubble ejection and early ink filling a efficiency by setting a nozzle orifice with pores for ink droplet ejection in an ink feeder channel or a pressure chamber. CONSTITUTION:A vibration plate 10 and a piezoelectric element 9 are deformed by application of a voltage to the piezoelectric element 9 stuck to the vibration plate 10, resulting in the change of the volume of the pressure chamber 6, and subsequent in flying of ink droplets through a nozzle orifice 7. After the flying of the droplets, ink is supplied to the pressure chamber 6 and the nozzle orifice 7 by a capillary force attributed to surface tension generated in the nozzle orifice 7 from an ink supply preparation chamber 12 via an ink supply channel. Consequently, an ink stream generates in the entire area of an ink flow path due to a return action at the time of air bubble generation or infiltration, thus being able to eject all the air bubbles from the ink flow path.
