1. A multi-way selector valve, comprising: a valve member that is rotated by an actuator such as a motor or the like in order to switch flow paths; and a valve body that rotatably holds the valve member, wherein a high-pressure passage portion to which a high-pressure fluid is introduced is formed in the valve member, a valve seat portion provided with a first inlet/outlet and a second inlet/outlet that are selectively communicated with an outlet side of the high-pressure passage portion, and a valve chest into which a low-pressure fluid is selectively introduced via the first inlet/outlet and the second inlet/outlet are provided in the valve body, during a transitional phase of flow path switching, an outlet-side end portion of the high-pressure passage portion of the valve member slides while being pressed against a portion between the first inlet/outlet and the second inlet/outlet in the valve seat portion, and an escape passage portion comprising a groove, notch, through-hole or the like for allowing a high-pressure refrigerant of the high-pressure passage portion to escape to the side of the valve chest during the transitional phase of flow path switching is formed in the valve seat portion.
