ABSTRACT:
A temperature responsive viscous drive coupling having a working chamber which substantially conforms to the rotor. The coupling has a housing which defines a central cavity divided by a plate into a reservoir and a working chamber. A rotor is rotatably supported relative to the housing and located within the working chamber. The housing and the plate closely conform to the configuration of the rotor to reduce to a minimum the space within the working chamber surrounding the rotor. Dimensions are maintained between the plate and the rotor and the housing and the rotor which are generally no greater than fifty to seventy thousands of an inch. These dimensions are within acceptable manufacturing tolerances to insure that rubbing does not occur between the rotor and the housing or the plate. In such an arrangement, the volume of the fluid in the working chamber when the coupling is in the static condition will be about one-third or less than the total volume of fluid within the coupling. The disclosure results in an increase in torque capacity and a substantial decrease in the time required to pump fluid out of the working chamber into the reservoir during start up.
