Liquid discharging apparatus
Abstract:
A liquid discharging apparatus in which a liquid is flowed in one direction in a circulation flow path at the time of non-discharge, and the flow path is refilled with liquid from both directions at the time of discharge. The liquid discharging apparatus includes a pressure adjustment unit that satisfies a condition “Pu>Pd, Pn>−Pd”, where Pu denotes a fluid pressure at a predetermined position on the upstream side of a discharge port, Pd denotes a fluid pressure at a predetermined position on the downstream side thereof, and Pn denotes a pressure equivalent to a capillary force of the discharge port for absorbing the liquid from the flow path into the discharge port immediately after the liquid has been discharged therefrom.
