ABSTRACT:
A viscous fluid coupling for use with a fan that cools as automobile engine includes a rotor driven by the engine. The rotor is housed in a housing formed by a case and a cover. A rear plate is mounted on the inner surface of the case and has an orifice. A front plate is mounted on the inner surface of the cover and has a hole through which viscous fluid can flow. A first reservoir is formed by the cover and the front plate. A second reservoir is formed by the rear plate and the case. Teeth are formed on the outer surface of the rotor. A protrusion is formed on the outer periphery of the rotor near the orifice.
