20120127242 | LIQUID FEED VALVE UNIT AND LIQUID EJECTION DEVICE - A liquid feed valve unit is configured to switch between a releasing mode for forcibly opening a valve and a blocking mode for closing the valve, and the valve can therefore be opened and closed in a short time as needed. Since the releasing mode is implemented by pushing the peripheral part and the pressure-receiving part of the flexible member, the flexible member can be prevented from flexing toward the outside of the liquid accommodating chamber even in the case that the pressure-receiving part is pushed. In this case, since a residual pressure can be prevented from forming in the liquid accommodating chamber, there is no need to suspend operation, and it is possible to immediately proceed to the next operation. A fast-operating liquid feed valve unit can thereby be obtained. | 05-24-2012 |
