Abstract
A fluid coupling device is provided of the type including a rotatable input member and a relatively rotatable output member cooperating with a cover to define a fluid chamber therein. The device includes a movable valve member mounted on a valve shaft which is rotatably supported by a support insert seated within an opening in the cover. The rotational position of the valve shaft is made temperature-responsive by means of a bimetal coil having a first end connected to the valve shaft and a second end mounted relative to the cover. The bimetal coil has a nominal width over the major portion of its length but includes an initial portion adjacent the first end having a width substantially less than the nominal width. The initial portion comprises between about one and one and one-half turns of the coil to permit the coil to be disposed closer to the cover without interfering with the support insert.
