Abstract

A liquid discharge apparatus includes a liquid chamber in communication with a nozzle configured to discharge liquid through the nozzle; a capacity change portion configured to change a capacity of the liquid chamber; an inflow path connected to the liquid chamber and configured to allow the liquid to be flown into the liquid chamber; an outflow path connected to the liquid chamber and configured to allow the liquid to be flown out from the liquid chamber; a first flow-path resistance change portion configured to change a flow-path resistance of the inflow path; a second flow-path resistance change portion configured to change a flow-path resistance of the outflow path; and a controller configured to control the capacity change portion, the first flow-path resistance change portion, and the second flow-path resistance change portion. The controller allows the liquid to be discharged through the nozzle by controlling the first flow-path resistance change portion and the second flow-path resistance change portion to increase the flow-path resistance of the inflow path and the flow-path resistance of the outflow path, controlling the capacity of the liquid chamber to increase the capacity of the liquid chamber, and then, in a state in which the flow-path resistance of the inflow path and the flow-path resistance of the outflow path remain increased, controlling the capacity change portion to decrease the capacity of the liquid chamber.
