Document Type and Number:
WIPO Patent Application WO/2003/035276
Kind Code:
A1
Abstract:
A method and a device for accurate delivery, dripping and spraying are provided. A liquid material delivering method wherein a liquid material is pressurized by a plunger sliding while closely contacting the inner wall surface of a liquid feed passageway establishing communication between a nozzle and a storage section to deliver the liquid material from the nozzle. The plunger is disposed in a space filled with the liquid material. The sliding surface of the plunger sliding while contacting the inner wall surface of the liquid feed passageway divides it into a nozzle−side liquid material part and a storage container−side liquid material part, and of the divided liquid, the liquid material in the nozzle−side liquid material part is delivered by the plunger advancing in the liquid feed passageway. A liquid material delivering device characterized by comprising a liquid material storage section for storing a liquid material, a nozzle section for delivering the liquid material, a liquid feed passageway for establishing communication between the storage section and the nozzle section, a plunger section having a seal section sliding while closely contacting the inner surface of the liquid feed passageway, and a plunger moving means for advancing and retracting the plunger section, further comprising a liquid feed passageway (2) for establishing communication between the nozzle−side terminal end vicinity of the liquid feed passageway and the liquid material storage section vicinity of the liquid feed passageway or the liquid material storage section, and a liquid feed valve disposed in the liquid feed passageway terminal end of the liquid feed passageway (2) or in the liquid feed passageway (2).
