Abstract
A fan fluid coupling for use with an automotive engine. The coupling comprises a sealed housing, a partition plate that partitions the inside of the housing into an oil reservoir chamber and a torque transmission chamber, a resilient tonguelike valve member, and a rod member. The partition plate is provided with an outflow-adjusting hole located close to the outer end of the partition plate. The hole is a slot extending circumferentially of the partition plate. One end of the valve member is fixed to the partition plate. The valve member is curved upward. The front end of the valve member is in resilient contact with the rod chamber against which a bimetallic strip is pressed.
