Title:
FLUID TRANSFER DEVICE, COATING DEVICE COMPRISING SAME, AND COATING METHOD
Document Type and Number:
WIPO Patent Application WO/2022/158492
Kind Code:
A1
Abstract:
[Problem] To provide a fluid transfer device, a coating device comprising the same, and a coating method which solve the pulsation issues that occur when a male-threaded rotor is eccentrically rotated inside a stator having a female-threaded through-hole, and a fluid material is discharged from a nozzle. [Solution] A fluid transfer device 1 comprising: an outer tube 10; a stator 11 that has a female-threaded through-hole 12 provided in the inner circumferential surface of the outer tube; and a male-threaded rotor 20 connected to a rotor drive unit and eccentrically rotating and abutting the inner circumferential surface of the stator. The fluid transfer device 1 can transfer fluid in a transport path comprising the stator 11 and the rotor 20, by rotating the rotor 20 inserted into the through-hole 12. The fluid transfer device 1 is configured such that the adhesive force between the rotor 20 and inlet and outlet sections of the stator 11 is smaller than the adhesive force between the rotor 20 and a central section of the stator 11.
