Abstract
A coupling assembly for operatively connecting an output shaft of an internal combustion engine to a member associated with the engine such as a cooling fan, in which a rotor is fixed to the output shaft and a first casing is fixed relative to the member associated with the engine and surrounds the rotor. A first reservoir is defined within the first casing and contains a coupling fluid for transferring the torque of the rotor to the casing. A second casing is fixed to the first casing and defines a second reservoir for the fluid, with the second casing having a plurality of openings formed therethrough for permitting the fluid to pass from the first reservoir to the second reservoir to reduce the amount of torque transferred from the rotor to the first casing. An inertia valve is responsive to angular acceleration of the rotor and selectively controls the amount of fluid passing through the openings and thus the amount of torque transferred.
