ABSTRACT:
A fluid coupling device of the type including a rotatable input coupling member, a cover associated therewith to define a fluid chamber, a valve plate separating the fluid chamber into an operating chamber and a reservoir chamber, and an output coupling member disposed in the operating chamber and rotatable relative to the input coupling member. The valve plate defines a discharge orifice permitting the flow of fluid from the operating chamber to the reservoir chamber and a generally flat valve member is located within the reservoir chamber and disposed to move in a plane substantially parallel to the plane of the valve plate to vary the flow area of the discharge orifice. The movement of the valve member defines a valve operating area and the cover includes a portion coextensive with the valve operating area and oriented substantially parallel to the plane of movement of the valve member. The cover portion is closely spaced from the valve member during movement thereof to prevent "blowoff" of the portion of the valve member adjacent the discharge orifice as fluid flows from the operating chamber to the reservoir chamber.
