ABSTRACT:
A viscous fluid clutch includes a housing which defines a chamber. A fan assembly is attached to the housing. A rotor is rotatably attached to the housing through a bearing. The bearing is disposed entirely within the chamber at a radially inner portion of the chamber. The viscous fluid is located within a radially outer portion of the chamber. The housing and the rotor form a labryinth passage between the outer portion of the chamber and the inner portion of the chamber. This labryinth passage encourages condensation of any oil vapors that may have formed at the shear point of the viscous fluid.
