ABSTRACT:
A bypass drive line for a torque converter type automatic transmission in which the bypass drive line includes a viscous coupling and automatic transmission fluid is selectivley passed through the periphery of the viscous coupling to provide a flow of cooling fluid around the coupling. The fluid flowing through the coupling enters at one face of the coupling adjacent the periphery of the coupling and then flows around the periphery of the coupling through a plurality of separate elongated narrow passages and then exits at the opposite face of the coupling.
The passages are defined by a series of interconnected concentric peripheral grooves defined within the coupling. In one disclosed embodiment, four separate circuitous paths are provided through the coupling and in a second disclosed embodiment two separate circuitous paths are provided.
