ABSTRACT:
A temperature responsive fluid coupling device which can precisely control the transmitting torque between an input coupling member driven and an output coupling member in three steps in response to changes of ambient temperature of the output coupling member. The fluid coupling device includes two labyrinth operating chambers functioning as a torque transmitting mechanism, and each operating chamber includes a fluid return opening and a pumping mechanism.
