Abstract
A control valve having first, second, and third outlet ports, which pass through a casing in a radial direction and formed axially at intervals in the casing, first, second and third communication ports, which respectively communicate between the flow path and the first outlet port, between the flow path and the second outlet port and between the flow path and the third outlet port according to a rotational position of the valve, are formed at intervals in the axial direction in the valve. The second outlet port is located between the first and third outlet ports in the axial direction and also located at a different position from the first and third outlet ports in a circumferential direction. An opening width of the second communication port in the axial direction is narrower than an axial interval between the first and third outlet ports.
