Abstract

PURPOSE: To prevent clogging easily by a method wherein a variable volume part generating volume change is formed on the way of a route for supplying a liquid and the liquid is generated within the route by operating said variable volume part.
CONSTITUTION: On the way of a liquid supply passage of an apparatus for injecting a liquid in a small droplet form, the variable volume part capable of generating volume change is provided. The variable volume part comprises bellows 10 having an ink introducing port 8, an ink discharge port 9 and is enlcosed by outer cylinders 11, 11'. When clogging is generated in the supply passage, pressure is applied to a direction shown by an arrow and a pressurized ink is discharged from the ink discharged port 9 to remove the clogging.
