Title:
CIRCULATION DEVICE
Document Type and Number:
WIPO Patent Application WO/2021/040005
Kind Code:
A1
Abstract:
This circulation device includes a first valve part, a second valve part, a first pressure measurement part, a second pressure measurement part, a detection part, and a control part. The first valve part controls the flow rate of a liquid fed from a reservoir part to a droplet discharge part. The second valve part controls the flow rate of a liquid fed from the droplet discharge part to the reservoir part. The first pressure measurement part measures, as a supply pressure, the fluid pressure of a liquid flowing between the first valve part and the droplet discharge part. The second pressure measurement part measures, as a recovery pressure, the fluid pressure of a liquid flowing between the second valve part and the droplet discharge part. The detection part detects information about the droplet discharge part. The control part controls the first valve part and the second valve part on the basis of the information detected by the detection part, and adjusts the supply pressure and the recovery pressure.
