<p>A fluid coupling device is disclosed of the type including a valve member (41) actuated by a valve shaft (39) extending through a cover (35), the position of the valve and valve shaft being controlled by a temperature responsive bimetal coil (43). The coil has a first end (47) attached to the valve shaft and a second end attached by means of a clip (53) to the cover. The valve shaft includes a pair of axially extending nubs (61) which are axially deformed into intimate engagement with the first end of the coil to prevent movement of the first end of the coil relative to the valve shaft. The second end of the coil includes a portion (55) parallel to the cover and a portion (57) parallel to the end of the coil. Each of the clip portions includes a projection (59), and the second end of the coil is projection resistance welded to the clip portion (57), and the clip portion (55) is projection resistance welded to the cover. This arrangement results in a simpler, more secure attachment of the coil to the valve shaft and to the cover, while reducing hysteresis of the coupling device.</p> |
