There is provided a liquid ejecting apparatus that is used for ejecting a liquid. The liquid ejecting apparatus includes a head unit that ejects the liquid, a liquid supply path that is used for directing the liquid to the head unit, a decompression defoaming unit that eliminates air bubbles from the liquid by decompressing at least a part of the liquid supply path, and a pressurizing unit that pressurizes at least a part of the liquid supply path.

A liquid supply device includes a liquid supply path for supplying liquid from an upstream side toward a downstream side where the liquid is consumed. A negative pressure chamber communicates with a decompression chamber through a communication hole and decompresses the decompression chamber. A communication hole valve body opens and closes the communication hole. A biasing member biases the valve body in a direction in which the valve body is always in a closed state. A flexible member forms a part of a wall surface of the negative pressure chamber and is displaced by a change in pressure within the negative pressure chamber. A communication hole valve body pressure member is displaced by the displacement of the flexible member to thereby press the valve body in a direction in which the valve body is in an open state against a biasing force of the biasing member.

A method removes bubbles from a liquid in a liquid ejecting apparatus. The liquid ejecting apparatus includes a liquid storing chamber that stores a liquid and a first pressure control chamber adjacent to the liquid storing chamber with a first partition wall portion having flexibility and gas permeability interposed therebetween. A pressure control valve opens or seals an inlet of the liquid storing chamber in response to displacement of the first partition wall portion. A switching valve connects to the first pressure control chamber. A depressurizing pump is connected to the switching valve. An ejection port on the downstream side of the liquid storing chamber ejects the liquid. The method includes communicating the first pressure control chamber with the depressurizing pump by controlling the switching valve, depressurizing the first pressure control chamber by driving the depressurizing pump, and sealing the first pressure control chamber by controlling the switching valve.

A liquid supply apparatus supplies liquid from a liquid container through a liquid supply path to a recording head. A liquid supply pump drives when a flexible member is displaced such that a volume of a pump chamber is increased or decreased while a part of the liquid supply path is set as the pump chamber. A negative pressure chamber is divided from the pump chamber by the flexible member. A first directional valve in the liquid supply path passes the liquid in one direction toward the supply pump from the liquid container. A second directional valve passes the liquid in one direction toward the liquid ejecting apparatus from the supply pump. A pressure adjustor between the first directional valve and the second directional valve increases a volume of the liquid container when a negative pressure larger than a predetermined pressure is applied to the negative pressure chamber.

There is provided a defoaming mechanism that is used for eliminating air bubbles from a liquid flowing through the inside of a liquid supply path included in a liquid ejecting apparatus. The defoaming mechanism includes a defoaming chamber that has a side wall extending in the vertical direction and is used for capturing the air bubbles contained in the liquid and a communication portion that allows the defoaming chamber and the liquid supply path to be communicated with each other in the side wall.

A liquid ejecting apparatus includes a liquid ejecting head with one nozzle group for ejecting one type liquid and another nozzle group for ejecting two types of liquid, thereby ejecting multiple types of liquid from the nozzle groups. A cap forms a sealing space that is suctioned by a suction pump. Flow-passages supply the liquid from a liquid container toward the liquid ejecting head. Flow-passage pumps in the downstream side of the liquid container in the flow-passages suction the liquid from the liquid container and discharge the liquid toward the downstream side. A choke valve has a valve chamber at the downstream side of the flow-passage pump to allow the liquid to flow therein. A flexible member changes a volume of the valve chamber by flexing. A discharge hole in an inner portion of the valve chamber is opened or closed by the flexing of the flexible member.
