PROBLEM TO BE SOLVED: To provide a flow channel switching valve that can secure sealing property by a simple configuration without using a seal material.SOLUTION: The flow channel switching valve 1 includes: a valve body 21 provided with a first flow channel 23 and a second flow channel 24; a valve main body 10 provided with a valve chamber 11 storing the valve body therein so as to be rotatable, an inflow port 12 opened toward a radial direction from the valve chamber 11 and a first outflow port 13, and a second outflow port 14 opened toward a rotation axis direction from the valve chamber; and a rotary driving device 30 for rotating the valve body inside the valve chamber 11 about the rotation axis. The flow channel switching valve selectively communicates the inflow port 12 with the first outflow port 13 via the first flow channel 23 by the rotation of the valve body 21 and the inflow port 12 with the second outflow port 14 via the second flow channel 24. The second flow channel 24 includes a slope 24a inclined relative to the rotation axis.SELECTED DRAWING: Figure 4 |
