Abstract
A viscous shear overrunning clutch having a housing and circular member is disclosed which provides a driving force in one direction and an overrunning clutch when the relative angular velocities of the clutch and housing are reversed. The design includes a housing having a circular member mounted therein. In one embodiment, spaced radially extending passageways are circumferentially defined in the circular member and allow fluid communication between a working chamber and a reservoir. Flow directing means are located on the outer periphery of the circular member adjacent the end of the radially extending passages to create pressures within the passages to move fluid between the working chamber and reservoir in response to differences in angular velocity between the housing member and circular member.
