Title:

DROPLET FORMING DEVICE AND DROPLET FORMING METHOD

Document Type and Number:

WIPO Patent Application WO/2013/111855

Kind Code:

A1

Abstract:

A droplet forming device (1) that forms a flying discharge of droplets from a nozzle (32) is provided with: a liquid chamber (29) that is linked to the nozzle (32) and supplies a liquid material (37); a plunger rod (6) a tip part (34) of which advances and retreats within the liquid chamber (29); a spring (8) that applies a biasing force to the plunger rod (6); a pressurization chamber (11) to which a compressed gas (10) that operates so as to move the plunger rod (6) backwards is supplied; a pressure source (15) that supplies the compressed gas (10) to the pressurization chamber (11); and a controller (45). The droplet forming device (1) and a droplet forming method using this device (1) are characterized by having magnetic field generating mechanisms (21, 22) that, when the plunger rod (6) approaches the most advanced position thereof, make a suction force operate in the advancing direction.
