Abstract

PURPOSE: To mitigate pulsation from an inlet with air and equalize the fluctuation in discharge pressure, by setting a barrier between the inlet and outlet of liquid with a height lower than the liquid level kept in an air chamber for partially shutting off the liquid flow.
CONSTITUTION: As a pump 2 is driven, ink 14 is pressure fed in a head 5 through an accumulator 3 and three-way valve 4 to form ink drops 16 for jet plotting. The discharge pressure of the pump 2 necessarily includes pulsation constituent at this moment. As the pressure enters an air chamber 13 from an inlet 9, the pulsation is mitigated with air in the chamber 13 and flows out from an outlet 10, without being transmitted directly to the outlet 10 because of a barrier 11 shown in the figure. Accordingly the ink 14 flowing through the outlet 10 does not include pulsation, and this equalized pressure transmitted to the head 5 can stabilize injection of the ink and plotting of images.
