A liquid dispensing circuit is provided with: a multi-way cock (1); a first line; a second line; a third line; a fourth line; a fifth line; and a casing which houses some of the above. When a cock (3) in the multi-way cock (1) is situated in a priming position, a distal opening (334) in a second part (332) of a first flow channel (33) communicates with a first port (P1), and a distal opening (335) in a third part (333) communicates with a second port (P2); thus, the first port (P1) and the second port (P2) are in an open state wherein the ports are connected to each other via the first flow channel (33), whereas a third port, a fourth port, and a sixth port are in an open state wherein the ports are connected to one another via a second flow channel. |
