ABSTRACT:
A fan fluid coupling for controlling the rotational speed of a fan that cools an automobile engine. The coupling comprises an enclosed housing, a partition plate that divides the inside of the housing into an oil reservoir chamber and a torque transmission chamber, a driving disk, a dam, a passage extending from the torque transmission chamber to the oil reservoir chamber, a bimetallic strip, a valve member, an idle oil reservoir chamber, and a circular hole formed in the driving disk for placing the idle oil reservoir chamber in communication with the torque transmission chamber only when the associated engine is at rest. At least one small hole is formed in the wall defining the idle oil reservoir chamber, and this hole is in communication with the torque transmission chamber.
