ABSTRACT:
A continuous slip bypass friction clutch for a hydrokinetic torque converter has annular interfaces that are adapted to engage and transmit torque while rotating in one direction and continuously slipping. One of the interfaces is provided with circuitous grooves that traverse back and forth across essentially the entire width of this interface to channel hydraulic fluid in the torque converter from a high pressure cavity at an outer diameter of the interfaces past the engaged clutch interfaces through flow paths defined thereby to a low pressure cavity at an inner diameter of the interfaces to thereby wet essentially the entire interface area of the clutch and to cool the clutch with a viscous pumping action that augments cooling differential pressure hydraulic fluid flow induced through the flow paths.
