PURPOSE:To provide a three-way cock in which a first fluid port and second or third fluid ports can be selectively connected only exclusively, and at the time of selecting the above path, the same connecting condition is not caused before or after changing a turning angle of a plug. CONSTITUTION:A three-way cock 10 comprises a plug inserted therein and an outer cylinder 11. The outer cylinder 11 includes an inlet port 11A, first outlet port 11B formed at a position peripherally distant in 90-degree arc from the port 11A and a second outlet port 11C formed at a position peripherally distant in 90- degree arc from the port B. The inlet port A is formed in the axial direction of the outer cylinder 11 at a position different from both outlet ports 11B, 11C. The plug 12 includes a first elongated port 12A and second and third ports 12B, 12C respectively formed in steps in the axial direction at positions peripherally distant in 90 and 180 degree-arcs from the port 12a. In this arrangement, the plug 12 is turned to switch an expected path. |
