Abstract

PURPOSE:To prevent the accumulation of bubbles in a pump chamber by providing a throttle with a narrow liquid flow passage at the inlet of the pump chamber to which the electrostriction vibrator of a liquid drop jet device is attached and also providing a land which divides the liquid at the inlet of the pump chamber. CONSTITUTION:In a device 1 which jets liquid drops from a nozzle 1a communicated with a pump chamber 1b by means of the volume change of the pump chamber 1b with a flexible wall to which an electrostriction vibrator driven by electric signals is attached, the shape of the inlet of a passage to supply ink to the pump chamber 1b is made into a semicircular one connected with a throttle 11, and in the center of the semicircle, a round land 12 is provided. When ink is supplied (a), an ink flow which passes the throttle 11 is divided along the land 12, is expanded by the capillarity of its latter half wall and then joined again.
