摘要：A novel viscous coupling for transmitting rotary torque via a viscous fluid hasfirst and second torque transmission members, a working chamber hermetically packedwith a viscous fluid, and first and second plates alternately disposed in the workingchamber. The transmission of rotary torque between the first and second transmissionmembers is carried out via viscous resistance of the viscous fluid between the first andsecond plates. The aforesaid viscous coupling is characterized by providing with a multi-plate clutch to adjust transmission power of the rotary torque between at least one ofthe plates and the torque transmission members. The coupling includes an externallyoperable engaging means for fastening the multi-plate clutch by pressing clutch platesof the multi-plate clutch. Also, the coupling has passages for leading the viscous fluid tocontact portions between the clutch plates and the plates.
