VISCOUS CLUTCH WITH RETURN BORE THROUGH ROTOR |
| 摘要 |
A viscous clutch (20) includes a housing assembly (28), a rotor assembly (26), a reservoir (38) to hold a supply of a shear fluid, a working chamber (40) operatively positioned between the housing assembly and the rotor assembly, and a fluid return bore (26-1B) that optionally extends radially through at least an outer diameter portion of the rotor assembly to the working chamber. Selective introduction of the shear fluid to the working chamber facilitates selective torque transmission between the housing assembly and the rotor assembly. The fluid return bore can form at least a portion of a fluid return path (50) from the working chamber to the reservoir. |

1. A viscous clutch comprising:
a housing assembly; a rotor assembly; a reservoir to hold a supply of a shear fluid; a working chamber operatively positioned between the housing assembly and the rotor assembly, wherein selective introduction of the shear fluid to the working chamber facilitates selective torque transmission between the housing assembly and the rotor assembly; and a fluid return bore that extends radially through at least an outer diameter portion of the rotor assembly to the working chamber, the fluid return bore forming at least a portion of a fluid return path from the working chamber to the reservoir. |
