PROBLEM TO BE SOLVED: To provide a channel switching valve stably securing sealing between a valve element and a valve seat, reducing a load applied to a drive source, simple in configuration, and preventing deterioration of the valve element.SOLUTION: A channel switching valve includes a valve element that includes two bowl-like sections 9a, 9b formed of an elastic body and opened in opposite directions, a valve rod 8 having a support section that supports the valve element, a valve body 2 having a valve chamber 2a that accommodates the valve element and the valve rod in a rotatable manner, an inlet port 3a communicating with the valve chamber, two outlet ports 4a, 5a communicating with the valve chamber, and two valve seats 2b, 2c connected/disconnected to/from the valve element in order to open/close the two outlet ports. A state in which one outlet port is closed and the other outlet port is opened by that the valve rod rotates around the axis thereof and either one of the bowl-like sections of the valve element is pressed to the valve seat of either one of the two outlet ports and a state in which the other outlet port is closed and one outlet port is opened by that the other bowl-like section of the valve element is pressed to the valve seat of the other outlet port are switched. |
