摘要： A seal structure that keeps a needle from sliding with respect to a seal and is easily detachable, and a device having the seal structure. A needle of a valve device is inserted through a seal. A valve device includes a fluid chamber having an outflow hole and au inflow hole, and the needle of which fore end reciprocates in the fluid chamber. The seal includes a main body made of an elastic body having a needle fitting insertion hole formed for the needle to be inserted and fit into. A flange portion is made of an elastic body annularly extending from the main body in a radial direction outward. One end opening diameter (D3) of the needle fitting insertion hole is smaller than the other end opening diameter (D2) of the needle fitting insertion hole.

摘要： A liquid material discharge device (20) has a nozzle member (35) provided with a discharge opening (33) through which a liquid material is discharged, a switching valve (51) in communication with the nozzle member, and a discharge controller. The discharge device further includes a pressurization section (60) having a pressurization passage (62) through which the liquid material under pressurization is supplied to the switching valve, and a negative pressure section (70) including a shunt passage (72) where a pressure can be set to be relatively lower than that in the pressurization passage. The switching valve is changed over between a first position at which the discharge opening communicates with the pressurization passage and the discharge opening is cut off from the shunt passage, and a second position where the discharge opening is communicated with the shunt passage and the discharge opening is cut off from the pressurization passage.

摘要： [Problem] To provide a droplet ejection device and a droplet ejection method with which a liquid material can be continuously delivered to an ejection head when the liquid material is delivered between arbitrary tanks. [Solution] Provided are a droplet ejection device and a droplet ejection method using the droplet ejection device, the droplet ejection device comprising a droplet ejection head; a supply tank that is in communication with a first positive pressure source; a collection tank that is in communication with a first negative pressure source; a replenishment tank that is in communication with the supply tank and the collection tank; an opening/closing valve A that opens and closes a flow passage communicating between the supply tank and the replenishment tank; an opening/closing valve B that opens and closes a flow passage communicating between the collection tank and the replenishment tank; a switching valve that switches communication between the replenishment tank and a second positive pressure source and communication between the replenishment tank and a second negative pressure source; and a control device, wherein the control device has an ejection mode in which a liquid material is ejected from the droplet ejection head, a replenishment mode in which the liquid material is delivered from the replenishment tank to the supply tank while the liquid material is delivered from the supply tank to the collection tank, and a collection mode in which the liquid material is delivered from the collection tank to the replenishment tank while the liquid material is delivered from the supply tank to the collection tank.
