Liquid ejecting apparatus with pressure adjusting valve

摘要

A liquid ejecting apparatus includes a liquid ejecting section that includes a nozzle that ejects a liquid; a supplying path that is capable of supplying the liquid accommodated in a liquid accommodating section to the liquid ejecting section; a pressure adjusting valve that is disposed in the supplying path, and includes a pressure chamber which is capable of storing the liquid, the pressure chamber being is provided with an outlet that draws out the stored liquid to the liquid ejecting section, and when a pressure in the internal portion of the pressure chamber decrease, the pressure adjusting valve being opened to adjust a pressure of the liquid supplied to the liquid ejecting section; a discharging path that connects to a communicating port which communicates with the pressure chamber in a separate position different from a position of the outlet; and a switching valve that is provided in the discharging path.

1. A liquid ejecting apparatus comprising:
a liquid ejecting section that includes a nozzle that ejects a liquid; a supplying path that is capable of supplying the liquid accommodated in a liquid accommodating section to the liquid ejecting section, wherein the supplying path has a first end coupled to the liquid accommodating section; a pressure adjusting valve that is disposed in the supplying path, and includes a pressure chamber which is capable of storing the liquid, wherein the pressure chamber is provided with an outlet that draws out the stored liquid to the liquid ejecting section, and wherein when the liquid is drawn out of the outlet to the liquid ejecting section to thereby cause a pressure in the internal portion of the pressure chamber to decrease, the pressure adjusting valve is opened to cause the supplying path and the pressure chamber to communicate with each other and thereby adjusts a pressure of the liquid supplied to the liquid ejecting section; a discharging path that connects to a communicating port which communicates with the pressure chamber in a separate position different from a position of the outlet; and a switching valve that is provided in the discharging path.
