Abstract
There is disclosed a temperature-controlled fan fluid coupling which supplies cooling air to the engine of an automobile according to the operating conditions at all times. The coupling includes a rotating shaft, a driving disk fixed to the shaft, and an enclosed housing consisting of a cover and a casing. The coupling further includes a dam for collecting oil, a circulation passage, a valve member for opening and closing a hole formed in a partition plate, and a temperature-sensing element. Radially protruding fins or recessed walls are formed to force oil to the dam.
