DEVICE FOR SUCKING LIQUID AND METHOD FOR SUCKING LIQUID

摘要

When a plurality of liquids are sucked simultaneously through a plurality of suction paths connected with one pump, ending of one suction may impede other suctions. A multiple valve for connecting each suction path with the pump in one to one correspondence is disposed between the plurality of suction paths and the pump. Suction is performed while changing over connection of the suction path and the pump sequentially in time division manner. Since the pump and a suction path are independent of other suction paths for some predetermined time, the liquid can be sucked without being affected by the end of suction in other suction paths.
