Abstract

PURPOSE:To improve energy efficiency and to increase speed in the formation of drops by a method wherein on an ink passage in an ink jet head, there is provided a fluid controlling medium having a value which is deformed by the operation of ink pressure. CONSTITUTION:When a volgage is applied from an electric power source 18 to a piezo element 11 and a wall 12 is curved to the side of a pressure chamber 13, the ink flow of the pressure chamber 13 to a nozzle 14 becomes smaller and smoother in fluid passage resistance by means of a fluid controlling means 21, while the flow of the pressure chamber 13 to a supply passage 15 becomes larger in the fluid passage resistance by means of a fluid controlling means 22. When the wall 12 returns to the original state, the ink, on the contrary, is made difficult to flow backward from the nozzle 14 and made easy to flow in from the supply passage 15. The fluid controlling means, for example, is so constituted that a circular plate valve 401, a fixed member 407 are laminated on a valve seat 404 having outlets 402 and the ink can flow out of the side of the valve seat 404 through a clearance 408.
