ABSTRACT:
A fluid coupling device is disclosed of the type including a valve member actuated by a valve shaft extending through the cover, the position of the valve and valve shaft being controlled by a temperature responsive bimetal coil. The coil has a first end attached to the valve shaft and a second end (free end) received within a receiving portion of a clip member. Disposed between the second end of the coil and the receiving portion of the clip member is a resilient elastomeric member having a relatively thin wall. The clip member includes at least one wing portion which is attached to the cover to define an enclosure. The enclosure is configured to engage the elastomeric member which is compressed against the second end portion of the coil on at least two sides. The elastomeric member fills the clearance between the coil and the clip, even if the thickness of the clearance is not uniform, to increase the coefficient of friction, and the total gripping force, between the clip and coil. At the same time, the resiliency of the elastomeric member prevents the gripping of the coil by the clip from being too rigid, in cases where the fit therebetween is extremely close.
