Patent ID: 8397955

Claim:
A liquid material discharge device comprising: a liquid material supply section for supplying the liquid material to be discharged; a measuring section having a measuring hole and a plunger sliding on an inner wall surface of the measuring hole to suck the liquid material into the measuring hole and to discharge the liquid material; a plunger driving section for moving the plunger; a discharge section having a discharge port for discharging the liquid material; a valve section for changing over communication between the liquid material supply section and the measuring section and communication between the measuring section and the discharge section, the valve section includes a block having the measuring hole therein; a valve driving section for operating the valve section; and a debubbling mechanism provided in a flow path running from the liquid material supply section to the measuring section, wherein the debubbling mechanism includes a first flow path communicating with the liquid material supply section side, a second flow path communicating with the measuring section side, and a body for making the first flow path and the second flow path communicate with each other, the body having a greater width than the first flow path, and a discharge port of the first flow path is located above a suction port of the second flow path, and wherein the debubbling mechanism includes communication mechanism for selectively establishing or cutting off communication between the interior and the exterior of a debubbling mechanism body, thus enabling a liquid surface position within the body to be adjusted.
