description PURPOSE:To prevent the cobwebbing phenomenon of a paste material and to improve its quantitative and discharging properties by synchronizing with the timing repeatedly feeding a paste material and opening and closing the discharging port by a shutter mechanism. CONSTITUTION:The releasing time of a solenoid valve 16 and the working time of a piezoelectric element 18 are set by a timer set switch. When a discharging switch is turned on, the solenoid valve 16 is driven, the air giving a pressure presses the paste material inside a syringe 10 via an air hose 14 to discharge the paste material from the discharging port 12 of a needle 11. When the releasing time of the solenoid valve 16 is finished, the piezoelectric element 18 is driven simultaneously with the solenoid valve 16 being closed and a small displacement is caused, this displacement is enlarged by a displacement enlarging mechanism 20, transmitted to a shutter machine 17 to close the discharging port 12 and the discharge is stopped. The cobwebbing phenomenon of the paste material is thus prevented and the dispersion in the discharging amt. is remarkably reduced.
