PURPOSE:To obtain a fluid supplying element, which is capable of conducting stable and high-speed printing by reducing influence of fluid pressure variation due to movement of a head, by connecting two fluid chambers with their respective openings by a special construction using two plates having a couple of orifices. CONSTITUTION:First and second fluid chambers 17 and 18 with their respective opening 23 and 24 are divided into two sections by two nozzle plates 26 and 27 which are placed opposite to each other with a fixed interval. Further, these two fluid chambers 17 and 18 are connected with each other by orifices 21 and 22, which are aligned with each other, through a fluid layer 19 formed by the nozzle plates 26 and 27. And further, a gap between the fluid chambers 17 and 18 is connected with a separate opening 25 preferably through third fluid chamber 20. |
