Abstract
A fluid clutch which is structurally simplified to lower its cost and enabled to stabilize its action by optimizing the arrangement of an electromagnetic valve and to have a long lifetime by preventing a premature deterioration of a bearing or the like. The inside of a sealed case 2, in which a drive disc 3 fixed on a rotary shaft 1 is accommodated and made rotatably on the rotary shaft 1, is divided by a partition 5 into a torque transmission chamber 4 and an oil supply chamber 6, so that the drive torque of the drive disc 3 is transmitted to the sealed case 2 by the oil to be fed from the oil supply chamber 6 to the torque transmission chamber 4. Midway of a discharge passage 7 for feeding the oil, as recovered by a dam mechanism, from the torque transmission chamber 4 to the oil supply chamber 7, a passage controlling electromagnetic valve 10 is arranged coaxially with the rotary shaft 1.
