Abstract
A fluid coupling includes an operation plate for defining storage and working chambers in a housing and having a communicating hole for fluid communication between the two, a driven wheel arranged adjacent to the operation plate, a torque-transfer part for transmitting torque of a rotor to the housing, and a valve mechanism for opening and closing the communicating hole. An auxiliary chamber, which is arranged in the driven wheel, brings working fluid out of the communicating hole to the torque-transfer part. A positioning mechanism ensures circumferential positioning of the operation plate and the driven wheel.
