ABSTRACT:
A fluid coupling device of the type including a rotatable coupling body defining a fluid operating chamber and a coupling member rotatable relative to the coupling body. A cover is associated with the coupling body and coupling member to define a fluid reservoir chamber, and a valve is operable to control fluid communication between the operating chamber and the reservoir chamber. The valve is mounted on a shaft which is rotatable relative to the cover and the rotational position of the shaft is controlled by a bimetallic coil having one end connected to the shaft and a second end which must be fixed relative to the cover. A bracket is fixedly attached to the cover and a clip member, in movable engagement with the bracket, receives the second end of the bimetal coil to prevent substantial rotational movement of the second end relative to the bracket. The clip member makes it possible to adjust the rotational position of the second end of the coil if, after assembly of the entire fluid coupling, it is found that the valve does not open within the specified temperature range.
