PURPOSE:To obtain the titled apparatus of easy assembly and maintenance by forming the primary ink chambers connected directly with the ink delivery outlets so as to dispose a secondary ink chamber between them and installing so as to make the connecting passages connecting the both ink chambers facing each other. CONSTITUTION:The pressure wave which is generated in the primary ink chambers 13, 14 by electromechanical transducer 25, 26 propagates to the ink delivery outlets 15, 16 and the connecting pathes 17, 18 at the same time. Pressure waves which pass through the connecting pathes 17, 18 collide each other in the secondary ink chamber 19, and the connecting pathes 17, 18 are very near and opposed, the pressure wave acts to block the other connecting path, then escape of the pressure wave to the ink reservoir direction is interfered. A clearance adjusting linear is used to keep a fixed thickness of the ink chamber 19, and the ink chambers 13, 14 are separable on the border of the ink chamber 19. |
