<p>PROBLEM TO BE SOLVED: To prevent insufficient supply of a working fluid to a centrifugal balance chamber caused by the higher viscosity of the working fluid by supplying the working fluid in a cold condition to the centrifugal balance chamber through an oil cooler, and in turn, generation of the drag of a clutch. SOLUTION: An opening/closing plate 519 formed of a bimetal in which two kinds of metallic plates 519a, 519b different in coefficient of thermal expansion are attached to each other is provided on a communication passage 12f to be connected to an oil passage 12b of an oil pump 12, and when the temperature of a working fluid is lower than a specified value, the opening/closing plate 519 is bent to the right in a condition (b), the communication passage 12f is opened to allow the working fluid flow in the X-direction. When the temperature of the working fluid is higher than the specified value, the opening/ closing plate 519 is upright in a condition (a), and the communication passage 12f is closed.</p> |
