Provided are a method and a device for discharging a fixed amount of liquid such that it is possible to divide and dispense a liquid material with a higher accuracy than is possible with conventional devices. The method for discharging a fixed amount of liquid uses a device provided with: a decompression valve for reducing the pressure of a compressed gas supplied by a compressed gas source; a discharging valve for controlling the flow rate of the gas decompressed at the decompression valve; a liquid storing container for discharging liquid from a nozzle through the pressing force of the gas supplied via the discharging valve; and a buffer tank positioned between the decompression valve and the discharging valve that has a volume greater than the volume of the liquid storage container. The method and device for discharging a fixed amount of liquid are characterized by suppressing the pressure reduction that occurs in the flow path for supplying the compressed gas to the aforementioned liquid storage container during the operation of the aforementioned decompression valve by increasing the flow resistance in the flow path that connects the aforementioned buffer tank with the aforementioned storage container so as to be greater than the flow resistance in the flow path that connects the aforementioned buffer tank with the aforementioned decompression valve. |
