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. |

1. A liquid injecting apparatus equipped with a liquid storing member, which stores liquid; a liquid injecting head, which injects liquid; a liquid supply passage, for supplying said liquid to the liquid injecting head from the liquid storing member; and a valve unit, which is provided in the liquid supply passage, the valve unit having:
a supply chamber, into which liquid to be supplied from the liquid storing member flows; a pressure chamber, in which liquid to be led out to the liquid injecting head is stored; and a valve, which connects the supply chamber to the pressure chamber by a negative pressure generated in the pressure chamber as the liquid is injected from the liquid injecting head, wherein the supply chamber has a supply chamber opening through which the liquid is supplied from the supply chamber to the pressure chamber, and wherein the valve selectively opens and closes the supply chamber opening. |
