PURPOSE:To provide a liquid supplying mechanism, which has a continuous injecting function so as to shorten the pressure responding time and to stabilize the ink supply pressure by providing a plurality of control devices between a plurality of pressure chambers so that the liquid may be introduced from a pressure chamber into a het nozzle through a check valve. CONSTITUTION:At the back of pressure control devices 4, two three-way electromagnetic valves 5 and 5' for interchanging two gas communication passages are connected in parallel so that their N/O and N/C terminals are connected commonly and are lead out of a gas discharging device 6 for an ink pressure chambers 7 and 7', which are connected with the valves 5 and 5'. There are accommodated ink reserving elastic containers 7-1 and 7'-1 so that ink 7-3 and 7'-3 may be sucked from an ink tank 8 through check valves 10 and 10' and may be fed to a nozzle 12 through check valves 16 and 16' during the injecting operation under pressure. Thus, by ensuring the continuous ink injecting function, it is possible to shorten the pressure responding time and to stabilize the ink supply. |
