Abstract
A viscous fluid coupling assembly is used for driving a cooling fan of automobiles in order to prevent the overcooling of the engine and to reduce the loss of engine power. The assembly comprises an input coupling member driven by an engine, an output coupling member being able to rotate relatively to the input coupling member, a dividing plate dividing the inside of the output coupling member into a reservoir chamber for a viscous fluid and a working chamber, first and second torque transmission surfaces to transmit a torque by means of the viscous fluid, first and second openings, and a thermal responsive valve, thereby controlling the viscous fluid from the reservoir chamber to the working chamber in three steps in response to changes in temperature.
