PROBLEM TO BE SOLVED: To provide a liquid jetting apparatus or the like forming a pressure-reduced space in a liquid storage apparatus, maintaining the pressure-reduced state of the pressure-reduced space and stably supplying deaerated liquid to a liquid jetting part. SOLUTION: The liquid jetting apparatus includes a liquid storage part 2, the liquid jetting part 3, a pump P and a control means 5. The liquid storage part 2 includes a first chamber 15, a second chamber 16, a gas-impermeable liquid storage body 17, a gas-permeable liquid storage body 18, a communicating passage 19, an air intake port part 10, an air outlet part 11 and a liquid outlet part 52. The control means 5 operates the pump P to eject air in the second chamber 16 to the outside of the second chamber 16 through the air outlet part 11. The second chamber 16 is thereby formed into the pressure-reduced space that can absorb gas dissolved in liquid in the gas-permeable liquid storage body 18. COPYRIGHT: (C)2010,JPO&INPIT |
