Document Type and Number:
WIPO Patent Application WO/2017/077730
Kind Code:
A1
Abstract:
This liquid supply device 10a has a first liquid flow path 21 and a second liquid flow path 22 that connect a suction port 13 and a discharge port 14. The first liquid flow path 21 is provided with a first pump 25 and the second liquid flow path 22 is provided with a second pump 26 that performs a suction operation when the first pump 25 performs a discharge operation and performs a discharge operation when first pump performs a suction operation. A three-way valve 42a serving as a switching valve mechanism 41 switches between a first pump flow path filling mode for filling the first liquid flow path 21 with a liquid, a second pump flow path filling mode for filling the second liquid flow path 22 with the liquid, and a continuous discharge mode that connects the first liquid flow path 21 and the second liquid flow path 22 with the suction port 13 and the discharge port 14, respectively.
