Abstract
An external-control-type fan coupling device is provided and has no restriction on the layout or positional relationship of an electromagnetic coil and a valve element of the device. As a result, the casing and the valve structure of the device can be simplified. Additionally, the design prevents leaking of oil and leaking of magnetism without adversely affecting performance.
