A fluid friction clutch comprises a driving section 1, a rotational shaft 2 rotated by the driving section 1, a driving 10 disc 5 rotationally driven by the rotational shaft, a casing 4 in which the driving disc is incorporated and which is rotatable about the rotational shaft, a fan 15 attached to the casing, and an oil-filled torque transmission gap defined between the driving disc 5 and the casing 4 for transmitting the driving 4 torque of the driving disc to the casing, wherein an oil supply 6 means is arranged for supplying oil from the outside to the inside of the casing and the oil supply means is connected by way of an oil supply pipe 16 to either side of the casing. The supply means is operated by a control unit receiving 6 information concerning the speeds of the shaft and the fan, and the temperature of cooling water. The casing may include a breather (30, Fig. 6). <IMAGE> |
