Patent ID: 10343400

Abstract:
There is provided a liquid discharge apparatus including: a liquid-chamber that communicates with a nozzle and a flow-chapel; a liquid chamber driving unit that changes a volume of the liquid-chamber; and a valve that changes a volume of the flow-channel. At least one of first control of increasing the volume of the liquid-chamber, such that a change amount of the volume of the liquid-chamber is equal to or larger than a volume of the liquid flowing from the flow-channel into the liquid-chamber due to the decrease in volume of the flow-channel by the valve, and second control of decreasing the volume of the liquid-chamber, such that a change amount of the volume of the liquid-chamber is equal to or larger than a volume of the liquid flowing from the liquid-chamber out to the flow-channel due to the increase in volume of the flow-channel by the valve, is executed.
