1. A control valve comprising:
a valve housing;
a coolant port formed in the valve housing through which coolant flows;
an oil cooler port formed in the valve housing;
a heater port formed in the valve housing;
a radiator port formed in the valve housing;
a bypass flow path through which the coolant port and the heater port communicate with each other; and
a ball valve formed with a valve inlet configured to communicate with the coolant
port,
wherein:
when the ball valve rotates inside the valve housing, the coolant port and the oil cooler port selectively communicate with each other, and the coolant port and the radiator port selectively communicate with to each other,
the ball valve includes a first section outlet, a second section outlet, and a third section outlet, which each communicate with the valve inlet, formed consecutively along an outer periphery of the ball valve,
a central axis of the oil cooler port passes through a center of the ball valve, and
a central axis of the ball valve perpendicular to a rotation shaft of the ball valve is offset from the central axis of the oil cooler by a predetermined angle.
