Title:
LIQUID MATERIAL DISCHARGE DEVICE
Document Type and Number:
WIPO Patent Application WO/2017/204399
Kind Code:
A1
Abstract:
The present invention relates to a liquid material discharge device configured such that a liquid material can be discharged to a target point by a rated amount. More particularly, the present invention provides a liquid material discharge device comprising: a cylindrical stator having a through-hole formed in a female screw shape in a flow direction defined from an inflow opening toward a discharge opening; and a rotor formed in a male screw shape and inserted into the through-hole of the stator so as to form a transfer space between the same and the stator, the rotor being configured to rotate and slide along the inner peripheral surface of the through-hole such that the liquid material is moved from the inflow opening toward the discharge opening along the transfer space, wherein the diameter of the rotor increases from the inflow opening toward the discharge opening such that the volume of the transfer space decreases in the flow direction; the liquid material moved along the transfer space is accordingly compressed such that, when the liquid material is discharged as the rotor rotates, bubbles can be removed from the liquid material in the transfer space; and compression of the liquid material by the gradual decrease of the volume of the transfer space in the flow direction maintains a constant density of the discharged liquid material and a constant amount of discharge.
