ABSTRACT:
A temperature-sensitive fan-coupling apparatus is provided with a driving side and a driven side. The driving side comprises a tightly sealed housing. The driven side comprises a rotary member from which fan blades extend. The rotary member includes a following disc disposed in the housing with a torque transmission gap existing between the following disc and the housing. A partition plate is mounted to the rotary member to define an oil reservoir therebetween. An aperture extends through the partition plate to provide communication between the oil reservoir and the torque transmission gap. A temperature-sensitive member is mounted external to the driven end of the apparatus and to one end of a connecting rod which extends through the rotary member and into the oil reservoir. A valve member is mounted to the end of the connecting rod in the oil reservoir and is disposed to selectively cover or open the hole in the partition plate to control the flow of fluid between the oil reservoir and the torque transmission gap. Movement of the valve member is controlled by the temperature-sensitive member.
