ABSTRACT:
A liquid delivering method and a liquid delivering device are provided, which solve the prior art problems including damages to a plunger and a valve seat. A liquid material delivering method includes the steps of advancing at high speed a liquid material delivering plunger with its distal end surface closely contacted with the liquid material, and subsequently abruptly stopping plunger driving means, thereby applying an inertial force to the liquid material to deliver the latter. A liquid delivering device includes a tubular metering section, a plunger internally contacting the metering section, a nozzle having a delivery port, a first valve for establishing communication between the metering section and the nozzle, a storage container for storing a liquid material, a liquid material feed valve (second valve) for establishing communication between the storage container and the metering section.
