Abstract: A fluid coupling device is disclosed of the type including an input coupling member (11) rotatably disposed within an output coupling assembly (13). A portion of the output coupling assembly comprises a cover member (17) which cooperates with a housing member (15) to define an operating chamber (33), and cooperates with a cover member (35) to define a reservoir chamber (37). A cover member (17) also defines a pair of fluid inlet ports (51). A valve actuating member (55) is received in a central bore (53) defined by the input shaft (21). The coupling device includes a valving arrangement (57) including a U-shaped fulcrum element (59) and a flat, elongated valve element (61). The valve (61) passes through slots (69) in fulcrum portions (65) of the fulcrum element.
