Fluid clutch

摘要

A fluid clutch comprises a driving disc rotationally driven by a driving section, a rotatable casing enhousing the driving disc, a blower attached to the casing, and an oil supply means for supplying an oil from an outside to a torque transmission gap between the driving disc and the casing. Further, a driving section may be connected by means of a flexible joint to either one of the casing or the disc. The fluid clutch can always attain optimum control by adjusting the amount of the oil at a high accuracy and rapidly depending on various kinds of operation conditions. A breezer also is provided for releasing gas from the torque transmission chamber when pressure exceeds a predetermined upper limit, and for enabling inflow of atmospheric air to the torque transmission chamber when pressure is less than a predetermined lower limit. The clutch is endurable to external vibrations.
