Abstract
PURPOSE: To constantly deliver infinitesimal high-viscosity fluid by providing the flow rate adjusting screw and the flow passage switching piston to the fluid delivery device cylinder.
CONSTITUTION: During the standing by period, the hollow flow passage switching piston 14 in the cylinder 12 is pushed to the driving side by the piston returning compressing spring 13, and the fluid passage in the adjusting screw 16 is shut off from the injection needle 20 by the piston 14. When driving air is injected from the driving side B, the passage switching piston 14 is pushed to he fluid side by the driving piston 18, and the fluid pressed in from A passes through the hollow part of the piston 14, the flow passage of the cylinder 12, and the outer wall of the flow passage switching piston through the adjusting screw 16, and is delivered from the injection needle 20. The infinitesimal adjusting of the fluid adjusting mechanism is made possible by the adjusting screw 16, and once it is adjusted, it would not move and quickly responds to the pneumatic driving so that constant infinitesimal continuous delivery becomes possible.
