Abstract:
1. A liquid supplying apparatus configured to supply liquid to a liquid supply object, the apparatus comprising: a supply flow channel which is connected to the liquid supply object; a first pressure applying device which applies pressure to the liquid inside the supply flow channel; a first pressure buffering unit including a first liquid chamber which is connected to the supply flow channel, a first gas chamber which stores a gas, and a first partition which separates the first liquid chamber and the first gas chamber from each other, the first partition being deformable or movable so as to vary a volume of the first liquid chamber; a first gas flow channel of which one end is connected to the first gas chamber; a first gas storage unit which is connected to the other end of the first gas flow channel; a first gas flow channel switching device which opens and closes to connect and disconnect the first gas chamber and the first gas storage unit to and from each other; a first atmosphere connection channel of which one end is connected to the first gas storage unit and the other end is connected to atmosphere; a first atmosphere connection channel switching device which opens and closes to connect and disconnect the first gas storage unit to and from the atmosphere; a first switching controlling device which controls operations of the first gas flow channel switching device and the first atmosphere connection channel switching device during initial position adjustment of the first partition and during pressurization of the liquid supply object; and a first pressure controlling device which controls an operation of the first pressure applying device in response to the operations of the first gas flow channel switching device and the first atmosphere connection channel switching device controlled by the first switching controlling device.
