The interior space is divided into a plurality of variable working spaces. A return port is formed in the rotary valve for feeding a cooling medium into an inlet port from the working space. A quantity of the cooling medium discharged from the working space through an outlet port is changed in accordance with the rotation of the rotary valve controlled by the actuator.
