Abstract
A cooling apparatus includes a circulation circuit, a pump, a flow rate adjustment valve, and a controller. The flow rate adjustment valve includes a valve member that rotates to change an open degree of the flow rate adjustment valve and a stopper that moves between a restriction position and a retraction position. The controller is configured to execute, when maintaining the open degree of the flow rate adjustment, a preparatory process of moving the stopper to the restriction position after arranging the stopper at the retraction position and arranging the valve member further in the valve-closing direction than the stopper through control of the pump discharge amount.
