Abstract
An external control type fan clutch device has a sealed housing with a torque transmission chamber incorporating a drive disk therein. The drive disk has an oil reserving chamber. The sealed housing is supported on a rotary shaft with the drive disk fixed thereto. A valve member (armature) controls opening and closing of an oil circulating flow passage hole provided on a side wall of the oil reserving chamber. The valve member has magnetism and is actuated by an electromagnet supported on the rotary shaft for opening or closing the oil circulating flow passage hole. A ring-like magnetic body is disposed between the electromagnet and the rotary shaft for efficiently transmitting a magnetic flux of the electromagnet to the armature of the valve member. The external control type fan clutch device achieves size reduction, weight reduction and power saving.
