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.
A fluid coupling device including a first rotatable member, cover means associated with said first member to define a fluid chamber therebetween, a valve plate disposed to separate said fluid chamber into a fluid operating chamber and a fluid reservoir chamber, a second rotatable member disposed in said fluid operating chamber and rotatable relative to said first member, valve means operable to control fluid communication between said operating chamber and said reservoir chamber, temperature-responsive means controlling said valve means, said temperature-responsive means including a bimetal element having a first end portion operatively connected to said valve means and a second end portion, bracket means fixed relative to said device and including a generally flat terminal portion extending away from said cover means, a clip member including means receiving said second end portion of said bimetal element and substantially preventing rotational movement of said second end portion relative to said first end portion, said clip member being disposed in movable engagement with said terminal portion of said bracket means to provide rotational adjustment of said second end portion of said bimetal element.
A fluid coupling device including a first rotatable member, cover means associated with said first member to define a fluid chamber therebetween, a valve plate disposed to separate said fluid chamber into a fluid operating chamber and a fluid resrvoir chamber, a second rotatable member disposed in said fluid operating chamber and rotatable relative to said first member, valve means operable to control fluid communication between said operating chamber and said reservoir chamber, temperature-responsive means controlling said valve means, said temperature-responsive means including a bimetal coil having an inner end portion operatively connected to said valve means and an outer end portion, bracket means fixedly attached to said cover means, a clip member in normally-fixed engagement with said bracket means and including means receiving said outer end portion of said bimetal coil to prevent rotational movement of said outer end portion relative to said inner end portion, said clip member being gnerally U-shaped to define an axis and being axially movable relative to said bracket means to provide angular adjustment of said outer end portion of said bimetal coil.
