Liquid ejecting apparatus

摘要

Provided is a liquid injecting apparatus equipped with a liquid injecting head, which is mounted on a carriage and moved reciprocally in a widthwise direction of a target, and a valve unit, which is mounted on the carriage to be supplied with liquid via a supply passage from a liquid retainer and to supply liquid to the liquid injecting head. The valve unit has a pressure chamber connected to the liquid retainer via the supply passage; a valve, which opens or closes the supply passage to supply liquid to the pressure chamber; and a flexible film member, which is displaced based on a negative pressure generated as liquid in the pressure chamber decreases to thereby operate the valve.

主权项

1. A liquid ejecting apparatus comprising:
a liquid ejecting head which ejects a liquid to a target; a liquid supply passage which supplies the liquid to the liquid ejecting head; a chamber which is provided in the liquid supply passage, the chamber temporarily storing the liquid; and a flow rate regulating part for forcibly changing a flow rate of the liquid that flows through the liquid supply passage, the flow rate regulating part being provided upstream from the chamber, wherein, while the flow regulating part forcibly reduces the flow rate of the liquid flowing through the liquid supply passage, a suction part provided at the liquid ejecting head side suctions the liquid from the liquid supply passage.
