Abstract
A fluid coupling includes a casing supported by a drive shaft, a cover fixed to the casing to form a chamber, a partition plate fixed to the cover to partition the chamber into a reservoir and an operation chamber, a rotor disposed in the operation chamber, a valve plate operated to open or close a passage provided in the partition plate, a stud supported by the cover and fixed to the valve plate and a bimetal spring fixed to the stud on an inner end and to the cover on an outer end thereof. A damper is disposed between the cover and the bimetal spring and includes a rubber block and a bracket fixed to a part of the cover. The damper prevents the vibration and breakage of the bimetal spring.
