Provided is a rotary valve which is easy to make smaller , and is capable of suppressing an increase in size even when a plurality of inflow ports or a plurality of outflow ports are provided. This rotary valve is equipped with a rotor (1) and a casing (2) for housing the rotor (1). The casing (2) is equipped with a rotor -housing space (2a) for rotatably housing the rotor (1). A location facing the outer- circumferential surface of the rotor (1) is provided with an inflow -side opening (23a) for allowing a fluid to flow into the rotor- housing space (2a) from the exterior and two outflow- side openings (25a ,26a) for allowing a fluid to flow out to the exterior from the rotor- housing space (2a). The rotor (1) is formed in a cylindrical shape having an interior space, and the end surface of the rotor (1) is equipped with an end -surface- side opening (14) which connects to the interior space. The outer- circumferential surface of the rotor (1) is equipped with a rotor- outer- circumferential opening (15) and a rotor -outer- circumferential closing surface (16) which open and close the outflow- side openings (25a , 26a) of the casing (2). |
