COOLANT CONTROL VALVE DEVICE

摘要

This coolant control valve device, which can maintain good sealing while limiting size increase, is configured so that: a rotor is housed to rotate freely in a housing in which a first discharge port and a second discharge port with a smaller diameter are formed; holes for controlling the flow of coolant to the first discharge port and the second discharge port are formed in the outer wall of the rotor; and a second seal part of the second discharge port abuts against the edge of a hole when the rotor is set to either rotation position in which coolant is discharged to the second discharge port.
