Abstract
A viscous fluid coupling used as a cooling fan for automobile engines, having a power output member divided into two water chambers by a partition. The refluxing of water between the two chambers are controlled by a valve which opens the first hole of the partition by being associated with a bimetal that operates by detecting the temperature of the air passing through the radiator and opens the second hole of the partition by being associated with a thermostat that operates by detecting the temperature of the water in the water pump, thereby effecting the accurate control of the rotation speed of the fan.
