Title:
A fluid injector and the pressurization-and-decompression method
Document Type and Number:
Japanese Patent JP6264802
Kind Code:
B2
Abstract:
A degassing process where gas is removed by depressurizing a liquid to be less than atmospheric pressure and a pressurizing process where the liquid is pressurized to be more than the atmospheric pressure are executed at a low cost and taking up less space. There is provided a head configured to eject a liquid from a nozzle, a supply section configured to supply the liquid to the head and including a degassing section in which the liquid supplied to the head is depressurized to be less than atmospheric pressure, and a pressurizing section in which the liquid is pressurized to be more than the atmospheric pressure, and a single pump having an action of depressurizing the degassing section and an action of pressurizing the pressurizing section.
