ABSTRACT:
A temperature sensitive fluid-type fan coupling device comprises a closed enclosure including a casing journalled on a rotary shaft through a bearing and having a cooling fan at its outer periphery, and a cover, a partition adapted to divide the interior of the closed enclosure into an oil chamber and a torque transmission chamber within which a drive disk is located and including a oil flow adjustment opening, a dam mounted to the inner periphery of the closed enclosure in a face-to-face relation to the outer periphery of the drive disk, an oil flowing toward the inner periphery of the closed enclosure during spinning of the closed enclosure, a circulation passage extending from the torque transmission chamber to the oil chamber through the dam, a valve element mounted within the oil chamber and having one end operable to open the flow adjustment opening when external temperature exceeds a given temperature and close the flow adjustment opening when external temperature is below the given temperature, a temperature sensitive element mounted to the front of the cover and deformed according to temperature fluctuation to move the valve element, and a magnet mounted to bias the valve element in a direction to open the flow adjustment opening.
